Iman rises and falls

Chapter 18 · about 13 min read

In short

  • Iman (faith) is alive. It grows with the Quran, dhikr, good deeds and good company, and it gets weaker with sins and forgetting Allah.
  • Iman has many branches. The highest is saying there is no god but Allah. The lowest is moving something harmful off the road.
  • A Muslim who sins is still a Muslim. Sins weaken iman, but they do not throw a person out of Islam. This is the middle way of Ahl al-Sunnah.
  • The words kufr (disbelief) and nifaq (hypocrisy) in the hadith are warnings to check our own actions and hearts. They are not labels to put on other Muslims.
  • The door of tawbah (repentance) is always open. However far you have gone, you can come back to Allah today.
Take the short lessonsThe key points of this chapter, a few screens at a time, with a quick check at the end.

Iman is alive

Iman means faith: believing in Allah, His angels, His books, His messengers, the Last Day and qadr (Allah's decree). You can read about these six in Islam, iman and ihsan.

This chapter is about something every Muslim feels. Some days your heart is soft. Salah feels sweet and you want to do good. Other days your heart feels hard and far away. That is normal. Iman is not a switch that is only on or off. It is more like a plant. It grows when you look after it, and it gets weak when you leave it.

Ahl al-Sunnah (the main body of Muslims who follow the Sunnah and the Companions) agree on these points:

  • Iman lives in the heart, is said with the tongue, and shows in actions.
  • Its strength goes up and down.
  • A Muslim who sins is still a Muslim.
  • We need both belief and good deeds.
A small difference in wording. Most scholars (the Athari and Ash'ari schools) say deeds are part of iman, so iman itself grows and shrinks. Many Hanafi and Maturidi scholars say iman is belief in the heart and saying it with the tongue, and deeds are its fruit. But they also say deeds are a must, and that the strength, light and certainty of iman grow and weaken. So in real life, both teach the same thing: look after your heart and your deeds. Learn the details from a teacher you trust.

What the Quran says

Allah speaks about iman increasing again and again in the Quran:

  • The true believers are those whose hearts shake when Allah is mentioned, and when His ayat (verses) are recited to them, it increases their iman1.
  • Allah sent down calm into the hearts of the believers, so that they add iman to their iman2.
  • When people tried to scare the believers, it only increased them in iman, and they said: Allah is enough for us3.
  • When a new surah came down, it increased the believers in iman and they were happy4.

If something can increase, it can also decrease. That is why scholars say: iman rises with obedience and falls with sins.

Even the Companions felt this. One of them, Hanzalah, was so worried about it that he thought he had become a hypocrite5.

The full story: Hanzalah thought he was a hypocrite

Hanzalah was one of the Companions who wrote things down for Nabi ﷺ. One day Abu Bakr met him and asked how he was. Hanzalah said: Hanzalah has become a hypocrite! Abu Bakr said: Subhan Allah, what are you saying?

Hanzalah explained: when we sit with Nabi ﷺ and he reminds us of Jannah and the Fire, it is as if we can see them with our own eyes. Then we go home to our wives, our children and our work, and we forget much of it.

Abu Bakr said: by Allah, I feel the same. So the two of them went to Nabi ﷺ and told him.

Nabi ﷺ said: if you stayed all the time the way you are with me, always remembering Allah, the angels would shake your hands in your beds and on your roads. But Hanzalah, there is a time for this and a time for that. He said it three times6.

What this teaches us

  • Ups and downs are normal. Even Abu Bakr, the best of the Companions, felt them.
  • Worrying about your iman is a good sign. A dead heart does not worry.
  • Islam is balanced. You are not asked to cry every minute. Family, work and rest have their place. The aim is to come back to Allah again and again.

The branches of iman

Nabi ﷺ said: iman has over seventy branches (in another report, over sixty). The best of them is saying la ilaha illallah (there is no god but Allah). The lowest is moving something harmful off the road. And haya (shyness and modesty that stops you doing wrong) is a branch of iman7.

This hadith teaches three big things:

  • Iman is wide. It is not only in the masjid. Belief, words, worship, manners and kindness to people are all part of it.
  • Small things count. Picking up a piece of glass from the street is a branch of iman. No good deed is too small.
  • People are at different levels. One person has many branches strong. Another has only a few. So never look down on anyone, and never feel your own good is enough.
WhereSome branches of iman
The heartBelieving in Allah, loving Allah and His Messenger, trusting Allah, hoping in His mercy, sincerity
The tongueThe shahada, reciting Quran, dhikr, dua, speaking the truth, kind words
The bodySalah, fasting, charity, helping people, keeping family ties, moving harm off the road

What makes iman grow

Iman needs food, like the body does. These are the things that feed it:

  • The Quran. When the ayat are recited, iman increases8. Even a few ayat a day, with the meaning, make a difference. Start on our Quran page.
  • Dhikr (remembering Allah). Allah says: truly, in the remembrance of Allah hearts find rest9. Nabi ﷺ said the one who remembers his Lord and the one who does not are like the living and the dead10.
  • Salah on time, and then extra good deeds. Allah says His servant keeps coming closer to Him with extra deeds until He loves him11.
  • Small and steady. Nabi ﷺ said the deed Allah loves most is the one done regularly, even if it is small12. Two rakat every night beat ten rakat once a month.
  • Good company. Nabi ﷺ said a good friend is like a perfume seller: he may give you some, you may buy some, or at least you smell something nice. A bad friend is like a blacksmith's fire: he may burn your clothes, or at least you smell smoke13.
  • Remembering death. Nabi ﷺ said: remember often the thing that cuts off pleasures, meaning death14. This is not to make you sad. It helps you see what really matters, and stops small worries from taking over.
  • Learning about Allah. The more you know His names and His mercy, the more you love Him. See The Names and Attributes of Allah.
  • Dua. Ask Allah to make your heart firm. Iman is a gift from Him, so ask the Giver.

What harms iman

Just as some things feed iman, some things weaken it:

  • Sins. Nabi ﷺ said a person who commits zina (sex outside marriage), steals or drinks alcohol is not a believer at the moment he does it15. Scholars explain: his iman is not complete at that moment. It is like a light that goes dim. It does not mean he has left Islam, as the next section shows.
  • Forgetting Allah. Long days with no salah on time, no Quran and no dhikr leave the heart dry.
  • Bad company. The blacksmith's smoke stays on your clothes16.
  • Too much of this world. Chasing money, likes and status until there is no time left for Allah.
  • Staying on a sin. Allah praises those who, when they do wrong, remember Allah, ask forgiveness, and do not keep doing it while they know17.

The good news: everything that weakens iman can be repaired. The last section of this chapter shows how.

A sinning Muslim is still a Muslim

In the early days of Islam, some people went to one extreme. They said a Muslim who commits a major sin is no longer a Muslim. Others went to the other extreme. They said sins do not harm iman at all.

Ahl al-Sunnah took the middle way: sins are serious and they weaken iman, but a Muslim who sins, and still believes, remains a Muslim. His matter is with Allah.

  • Allah forgives all sins except shirk (worshipping others with Him), to whom He wills18. So any sin less than shirk is under His forgiveness.
  • Two groups of believers fighting are still called believers by Allah19, and Allah says: the believers are brothers20.
  • Nabi ﷺ said: whoever dies without worshipping anything with Allah will enter Jannah. Abu Dharr asked: even if he committed zina and stole? He said: even if he committed zina and stole21.
  • About big sins, Nabi ﷺ said: if a person is punished for it in this world, that is a kaffarah (it wipes the sin). If Allah covers it, it is up to Allah: He may forgive or punish22.
  • Whoever has even a tiny grain of iman in the heart will in the end be taken out of the Fire23.

None of this makes sin small. It means we hate the sin, not the sinner, and we never give up on anyone, including ourselves.

The full story: do not curse him, he loves Allah

In the time of Nabi ﷺ there was a man called Abdullah. He used to make Nabi ﷺ laugh. But he had a weakness: he drank alcohol. He was punished for it, and later he was brought again for the same thing.

A man in the crowd said: O Allah, curse him! How often he is brought here!

Nabi ﷺ said: do not curse him. By Allah, I know that he loves Allah and His Messenger24.

What this teaches us

  • A person can sin and still love Allah. The sin was real and was punished. But his love for Allah was real too.
  • We do not curse Muslims who struggle. We pray for them.
  • Do not let shaytan tell you: you sinned, so you are a hypocrite, so give up. That is a trick. Keep your salah and keep coming back.

Kufr and nifaq: warnings for the heart

Two serious words appear in the Quran and hadith:

  • Kufr: disbelief, rejecting Allah or His message.
  • Nifaq: hypocrisy, showing Islam on the outside while hiding disbelief inside.

Sometimes the hadith use these words for sins done by Muslims. For example, Nabi ﷺ said: insulting a Muslim is a sin, and fighting him is kufr25. Yet Allah calls two fighting groups believers26. So scholars explain: here the word is a strong warning. It means this is an action of disbelievers, very serious, but it does not on its own take a Muslim out of Islam.

In the same way, Nabi ﷺ named the signs of a hypocrite: when he speaks he lies, when he makes a promise he breaks it, and when he is trusted he cheats27. In another report he added: when he argues he becomes nasty and unfair28.

How should we use these hadith?

  • As a mirror, not a stick. Read them and ask: do I lie? Do I break promises? Then fix it.
  • The Companions feared nifaq for themselves, like Hanzalah did29. They did not go around calling others hypocrites.
  • Allah sees the heart. Nabi ﷺ said Allah does not look at your faces or your wealth, but He looks at your hearts and your deeds30. We cannot see anyone's heart, so we cannot judge it.

Never call a Muslim a kafir

Calling a Muslim a kafir (disbeliever) is called takfir. It is one of the most dangerous things a tongue can do.

Nabi ﷺ said: if a man says to his brother, O kafir, then it comes back on one of them31. In another report: if the other person was not like that, it comes back on the one who said it32.

The full story: did you open up his heart?

Usamah ibn Zayd was a young Companion whom Nabi ﷺ loved very much. In one battle, Usamah and another man chased an enemy fighter. When they caught him, the man said: la ilaha illallah.

The other Companion stopped. But Usamah struck him and killed him, thinking: he only said it to save himself.

When Nabi ﷺ heard, he asked: did he say la ilaha illallah, and you killed him? Usamah said: he only said it out of fear of the weapon. Nabi ﷺ said: did you cut open his heart to see whether it meant it or not?33.

He kept repeating it, until Usamah said: I wished I had only become Muslim that day34.

What this teaches us

  • We judge by what people show, not by guesses about their hearts.
  • La ilaha illallah protects a person. No one may take that away from them by suspicion.

So what should an ordinary Muslim do?

  • Never say about any Muslim: he is a kafir, or: she has left Islam. Not online, not in anger, not as a joke.
  • Saying that a certain action is kufr is one thing. Saying that a certain person is a kafir is something else. Many conditions must be checked first: did they know? Did they mean it? Were they forced? Were they confused? Only senior scholars and courts can look at that. It is not our job.
  • If someone says or does something wrong, advise them kindly and make dua for them.

The door back: tawbah

Whatever has weakened your iman, the way back is tawbah (repentance), turning back to Allah. Allah says:

Say: O My servants who have wronged themselves, do not lose hope in the mercy of Allah. Allah forgives all sins35.

  • His hand is open day and night. Nabi ﷺ said Allah stretches out His hand at night, so that the one who sinned in the day can repent, and He stretches out His hand in the day, so that the one who sinned at night can repent, until the sun rises from the west36.
  • Allah is happy with your return. He is happier with a servant's tawbah than a man who lost his camel, with all his food and water, in the desert, and then found it again37.
  • Even again and again. A servant sins and says: my Lord, forgive me. Allah says: My servant knows he has a Lord who forgives. I have forgiven him. Then he sins again and asks again, and Allah forgives again38.
  • Bad deeds can turn into good ones. For those who repent, believe and do good, Allah changes their bad deeds into good deeds39.
  • Allah loves those who turn back. Nabi ﷺ said: if you never sinned, Allah would bring people who sin and then ask forgiveness, and He would forgive them40. This is not permission to sin. It shows how much Allah loves forgiving.

How to make tawbah

  • Stop the sin.
  • Feel sorry in your heart.
  • Decide not to go back to it.
  • If you wronged a person, give back their right or ask them to forgive you.
  • Then do a good deed. Pray two rakat, give some charity, and keep going.

If you fall again, repent again. Never stop coming back. Allah calls it sincere tawbah41, and He never gets tired of forgiving.

Common questions

I used to cry in salah. Now I feel nothing. Have I lost my iman?
No. Feeling low is not the same as losing iman. Even Abu Bakr and Hanzalah felt it42. The fact that it worries you is a sign of iman. Keep your five prayers, add a little Quran and dhikr each day, and ask Allah to soften your heart. Feelings come back.
I keep falling into the same sin. Is my tawbah fake?
No. If you are sorry when you repent and you really mean to stop, your tawbah is real. If you fall again, repent again43. Also change what leads you to it: the app, the place, the friends. Small changes help.
My friend drinks alcohol but still prays. Is he a hypocrite?
Do not call him that. Drinking is a major sin, but he is still a Muslim, and his salah is a good thing to protect. Remember: do not curse him, he loves Allah and His Messenger44. Be a good friend, advise him kindly, and make dua for him.
Someone online keeps calling other Muslims kafir. What should I do?
Do not join in, and do not argue in anger. Calling a Muslim a kafir comes back on the one who says it if it is not true45. Those questions belong to senior scholars. Unfollow, mute, or kindly share this hadith.
I read the signs of a hypocrite and I recognized myself. Now I am scared.
Those hadith are a mirror to help you fix things, not a judgement on you. Being scared of nifaq is a good sign: the Companions felt it too. Start with one sign. If you lie, practice telling the truth this week. Keep the promises you make.
I did something very bad before I became practicing. Can Allah forgive that?
Yes. Allah forgives all sins for the one who repents46, and He can even change bad deeds into good ones47. If the sin hurt someone, try to make it right. Then turn the page.
How do I keep my iman up when I work long hours?
Keep it small and steady48. Pray on time at work. Listen to Quran on your commute. Say Subhan Allah and Alhamdulillah while you walk. Find one or two friends who remind you of Allah.
