Nawawi Hadith 27: The Heart's Fatwa

Part One: Righteousness and the Restless Soul

Brothers,

Today’s khutbah is based on the 27th hadith in Imam Nawawi’s 40 Hadith:

On the authority of Al-Nawwas ibn Sam'an (may Allah be pleased with him) that the Prophet ﷺ said: 'Righteousness is good character, and sin is that which wavers in your soul, and which you dislike people finding out about.' (Muslim)

Imam Nawawi paired this with a second narration on the same subject, from the companion Wabisah ibn Ma’bad:

Wabisah ibn Ma'bad said: I came to the Messenger of Allah ﷺ and he said, 'You have come to ask about righteousness?' I said, 'Yes.' He said, 'Ask your heart for a verdict. Righteousness is that about which the soul feels at ease and the heart feels tranquil. And sin is that which wavers in the soul and moves back and forth in the chest, even though people repeatedly give you their opinion in its favor.' (Ahmad & Al-Darimi)

Two companions, two encounters with the Prophet ﷺ, one message: right and wrong are not decided by what is popular, what is convenient, or what other people tell you is fine. There is a built-in instrument for detecting sin, and Allah placed it inside every one of us.

Part 1: Righteousness Is Good Character

The Prophet ﷺ defines al-birr, righteousness, in the simplest possible terms: good character.

And indeed, you are of a great moral character. (Al-Qalam, 68:4)

This was Allah’s own description of His Messenger ﷺ. Character was not a side matter in his mission. It was the substance of it.

I have only been sent to perfect good character. (Ahmad)

Righteousness, in this hadith, is not defined first by ritual, though ritual matters immensely. It is defined by how you treat people, how you speak, how you control your temper, how honest you are, how patient you are under pressure. A man can pray and fast and still fail this test if his character is corrupt. A man of true taqwa lets his worship shape his character until the two cannot be separated.

Part 2: The Restless Signal Inside You

Then the Prophet ﷺ defines sin: that which wavers in your soul, and that you dislike people finding out about.

Notice how precise this is. Sin produces a specific internal sensation: unease, hesitation, a lack of settledness. And it produces a specific social instinct: concealment. You do not want witnesses.

And I do not absolve myself. Indeed, the soul is a persistent inciter to evil, except those upon whom my Lord has mercy. Indeed, my Lord is Forgiving and Merciful. (Yusuf, 12:53)

The nafs, the lower self, pulls toward wrong. But Allah placed alongside it another faculty: the conscience that flinches, that hesitates, that whispers “this is not right” even while the nafs is arguing for it. That flinch is a mercy. It is Allah warning you before the act, not only judging you after it.

And I swear by the reproaching soul. (Al-Qiyaama, 75:2)

Allah swears by this self-reproaching soul, the one that regrets, that questions itself, that will not let you sin in peace. If you still feel that voice, be grateful. Its silence is what you should fear, not its noise.

Part 3: Ask Your Heart for a Fatwa

Wabisah’s hadith gives us the method: istafti qalbaka, ask your heart for a fatwa. Before you consult a friend who will tell you what you want to hear, consult the organ Allah gave you specifically for this purpose.

Those who believe and whose hearts find rest in the remembrance of Allah. Verily, in the remembrance of Allah do hearts find rest. (Ar-Ra'd, 13:28)

A heart that is regularly connected to Allah, through dhikr, through prayer, through honest self-examination, becomes a reliable instrument. A heart clouded by constant sin becomes a broken one, and a broken instrument gives false readings. This is why some men no longer feel shame for what should shame them. Their instrument has been damaged by repeated misuse, not because sin stopped being sin.

The heart of the believer is alive and sensitive. It recoils from sin the way healthy skin recoils from fire. The heart of the heedless has grown numb, and feels nothing at all. (Ibn al-Qayyim, Madarij al-Salikin)

Part 4: When the Soul Is at Ease

The hadith gives us the positive test as well: righteousness is what the soul and heart are at ease with, tranquil about, settled in.

˹To the righteous it will be said,˺ 'O reassured soul, return to your Lord, well pleased and pleasing to Him.' (Al-Fajr, 89:27-28)

That tranquility is not the same as comfort. Some righteous acts are difficult, even painful, and yet the heart is at peace doing them because it knows they are right. Some sinful acts feel pleasurable in the moment, and yet the heart is never fully at peace, because underneath the pleasure is a low current of unease that never fully switches off.

Part 5: Even If They Give You a Hundred Opinions

The hadith closes with a warning that people will give you fatwas in favor of the sin. Wabisah was told: sin is what wavers in the soul, even if people repeatedly tell you otherwise.

And if you obey most of those on earth, they will mislead you from the way of Allah. They follow nothing but assumption, and they are not but falsifying. (Al-An'aam, 6:116)

A hundred people telling you something is fine does not change what your own conscience already knows. Popularity is not proof. Consensus of the crowd around you, especially a crowd with its own interests in normalizing what is wrong, is not revelation.

Part Two: Training a Trustworthy Conscience

Brothers,

This hadith is not only a definition. It is a diagnostic tool, one you can use today, right now, on any decision in front of you. Before you act, ask: does my heart feel settled about this, or does it waver? Would I be comfortable if every person around me knew exactly what I was about to do?

Part 6: The Danger of a Silenced Conscience

The greater danger is not the first sin. It is the tenth, the hundredth, the one committed so often that the wavering stops. Repetition can numb the very instrument the Prophet ﷺ told us to consult.

No! Rather, the stain has covered their hearts because of what they used to earn. (Al-Mutaffifin, 83:14)

Ar-ran, the rust and covering that builds on the heart from repeated sin, is real. It does not happen in one act. It builds layer by layer until the heart that once flinched at wrong no longer notices it at all. This is why sincere tawbah matters immediately, while the flinch is still there to guide you back.

Part 7: The Prison Context, Where the Fatwa Comes From

Brothers, this environment tests exactly what this hadith describes. You will hear a hundred opinions here about what is acceptable: what is fine to say, fine to do, fine to trade, fine to look the other way about. Some of those opinions will come from men who present themselves as knowledgeable. Some will come from peer pressure disguised as brotherhood.

The Prophet ﷺ told Wabisah, in this very setting of confusion and competing voices, to consult his own heart, the one Allah placed inside him and no one else can access. Not the loudest voice in the unit. Not the man with the most respect on the yard. Your own heart, if you keep it alive with dhikr and honest prayer, will tell you the truth before anyone else does.

When you feel that wavering before an action, when your chest tightens and you find yourself hoping no one is watching, that is not weakness. That is Allah’s mercy speaking to you directly. Listen to it before you act, not only after.

Part 8: Keeping the Instrument Alive

How do you keep your heart a trustworthy judge?

Return to dhikr daily, even a few minutes, so the heart stays connected to its source.

Examine yourself honestly each night: what did I do today that made my chest tight? What made it settled?

When you feel the wavering, stop the action immediately rather than negotiating with it.

Surround yourself, as much as this place allows, with men whose consciences are also alive, because a numbed conscience spreads faster than a living one.

And when you fail, as every son of Adam fails, return quickly, because the flinch you still feel is proof your heart is not yet ruined.

Part 9: The Sound Heart on the Day of Reckoning

Brothers, all of this training has one final destination in mind. On the Day of Judgment, nothing you owned in this life will matter except the condition of this same heart the Prophet ﷺ told Wabisah to consult.

The Day when neither wealth nor children will benefit anyone, except him who comes to Allah with a sound heart. (Ash-Shu'araa, 26:88-89)

Not your wealth. Not your family. Not your reputation among men. Only the heart, and whether you kept it clean, sensitive, and honest, or whether you let it grow numb to what it once recoiled from. This hadith is not a small piece of etiquette. It is training for the only asset that will accompany you into the grave and stand before Allah on your behalf.

The believer wakes up grieving over his own soul, fearful of what it might lead him toward, while the sinner wakes up secure, never questioning himself at all. (Hasan al-Basri)

Let your heart remain the kind that questions itself, that wakes up wary of its own weakness, rather than the kind that has grown so comfortable with sin that it no longer notices when it stumbles. That vigilance, uncomfortable as it feels, is the very sign that your fatwa-giver is still alive and still trustworthy.

May Allah keep our hearts alive, sensitive, and honest until we meet Him.

O Allah, make our character a true reflection of our worship.

O Allah, keep our hearts alive and sensitive to sin, and never let them grow numb.

O Allah, teach us to consult our conscience before we consult the crowd.

O Allah, give us the courage to stop the moment we feel the wavering in our chest.

O Allah, do not let repeated sin cover our hearts with rust.

O Allah, grant us tranquility in obedience and restlessness in disobedience, so we always know the difference.

O Allah, purify our intentions and perfect our character as You perfected the character of Your Messenger ﷺ.

O Allah, let us meet You with a sound heart, free of envy, malice, and hidden disease.

O Allah, make us among those who wake each morning fearful of their own shortcomings and eager to correct them.
