The Second Greater Sin: Yā's — Despairing of Allah's Mercy

From the series: Greater Sins | Based on Gunah-e-Kabira by Ayatollah Dastaghaib Shirazi (May Allah be pleased with him)

Have You Ever Felt Like You’ve Gone Too Far?

We’ve all been there. That moment after a mistake — sometimes a big one — where a voice inside whispers: “It’s too late for you. You’ve done too much. Allah won’t forgive this.”

That feeling has a name in Islamic scholarship. It’s called Yā’s — despair of Allah’s mercy. And according to Ayatollah Dastaghaib Shirazi, it is the second greatest sin in Islam, sitting right behind Shirk.

That might surprise you. Not murder. Not adultery. Not stealing. Despair.

But when you truly understand what despair means — what it says about your belief in Allah — it starts to make complete sense.

What Is Yā’s?

Yā’s (يأس) simply means losing hope. But in the context of this sin, it means losing hope, specifically in Allah’s mercy and forgiveness. It’s the belief — even if you feel it rather than consciously think it — that your sins are too great, your record too dark, and that Allah’s forgiveness simply doesn’t extend to someone like you.

It sounds like humility. It can feel like humility. But it isn’t. It is, in reality, a subtle form of disbelief — because it fundamentally misunderstands who Allah is.

Think about it this way. If someone told you that the ocean couldn’t fill a small cup, you’d laugh. The comparison makes no sense. Similarly, when we say our sins are “too much” for Allah’s mercy, we are — without realising it — placing a limit on something that has no limit whatsoever.

What Does the Quran Say?

This is where the Quran becomes incredibly personal and incredibly beautiful. In Surah az-Zumar, Chapter 39, The Companies, Verse 53), Allah doesn’t send a scholar to address sinners. He speaks directly:

“Say: O My servants who have acted extravagantly against their own souls — do not despair of the mercy of Allah. Surely Allah forgives all faults. Surely He is the Forgiving, the Merciful.”

Notice something remarkable here. Ayatollah Dastaghaib Shirazi points out that Allah does not say “O sinners” or “O wrongdoers.” He says “O My servants.” Even in the address to people drowning in sin, Allah reminds them — you are still Mine. You still belong to Me.

Then in Surah Yusuf, Chapter 12, Verse 87, Prophet Ya’qub (AS) tells his sons:

“Do not despair of the mercy of Allah. Indeed, none despairs of Allah’s mercy except the disbelieving people.”

That word — disbelieving — is the key. Despair isn’t just sadness or regret. It is, at its root, a failure of faith. It means you no longer truly believe in Al-Rahman, Al-Rahim — the Most Compassionate, the Most Merciful.

What Did the Ahlul Bayt (AS) Teach Us?

The Imams (AS) were beautifully consistent on this point. Imam Ali al-Ridha (AS), in a famous narration, lists Yā’s — despair — right after Shirk in the catalogue of major sins, underlining how deeply despair reflects a loss of faith in Allah’s own attributes.

Imam Ali (AS) in Nahj al-Balagha beautifully says:

“The most hopeful of all people should be the one who knows Allah best.” Knowing Allah — His generosity, His patience, His love for His creation — makes despair almost impossible. It is ignorance of Allah that breeds it.

There is also a deeply moving narration about a man who had committed so many sins throughout his life that when death approached, he was overwhelmed with despair. He told his family: “When I die, burn my body and scatter my ashes over the sea — so that Allah cannot resurrect me and punish me.” He genuinely believed that this plan could somehow escape Allah’s power. And yet — when he died, and his family carried out his wishes — Allah gathered every scattered particle of him, resurrected him, and asked him why he did this. The man said: “Out of fear of You, O Lord.” And Allah, in His infinite mercy, forgave him entirely.

The lesson? Even a man whose understanding of Allah was deeply confused — but whose heart still feared and was still somehow connected — was met with mercy.

Why Is Despair Such a Serious Sin?

Ayatollah Dastaghaib Shirazi explains something very important here. Despair doesn’t just hurt you emotionally — it paralyses you spiritually. When a person loses hope in Allah’s forgiveness, one of two things tends to happen:

1. They stop trying altogether:

Why pray? Why fast? Why make tawbah? If I’m already beyond saving, what’s the point? Despair becomes the door through which Shaytan enters and finishes the job. It is, in fact, one of Shaytan’s most powerful and favourite weapons. He knows that a person who still has hope will eventually turn back to Allah. But a person in despair? He has them.

2. They keep sinning without guilt:

Sometimes despair doesn’t paralyse — it goes the other direction. The person thinks: I’ve already ruined myself, so what does one more sin matter? This is equally dangerous because it accelerates a downward spiral far from Allah.

In both cases, the root problem is the same — a fundamentally flawed picture of who Allah is.

The Other Side of the Coin

It’s worth noting — and Ayatollah Dastaghaib Shirazi is careful to mention this — that the opposite extreme is also dangerous. That is, becoming so confident of Allah’s mercy that you sin freely with no concern, thinking, “Allah will just forgive me anyway.” This false sense of security is itself a separate sin called Al-Amn min Makrillah — which is actually the Fourth Greater Sin in this series.

The believer’s heart is meant to live in balance — between hope (raja’) and fear (khawf). Not crushing, paralysing fear. Not reckless, careless hope. But a healthy, mature balance that keeps us moving forward, repenting when we fall, and never giving up on our connection with Allah.

Imam Ja’far as-Sadiq (AS) described the believer’s heart as a bird with two wings — one wing of hope and one wing of fear. A bird with only one wing cannot fly. It is only with both that we soar.

How Do We Overcome Despair?

If you find yourself slipping into Yā’s — or if someone you love is there right now — here are some reminders rooted in the teachings of the Ahlul Bayt:

Recite this du’a of Prophet Yunus (AS):

“La ilaha illa anta, subhanaka, inni kuntu minaz-zalimin.” There is no god but You. Glory be to You. Indeed, I was among the wrongdoers.

This was the cry of a Prophet who found himself in the belly of a whale in the depths of the ocean — and Allah heard him and saved him. If Allah responded to that call, He will respond to yours.

Remember that Tawbah requires no appointment:

You don’t need to wait until Ramadan. You don’t need to become a better person first and then turn to Allah. You turn to Allah broken, messy, and mid-fall — and He meets you there.

Think of Allah’s names:

Al-Ghaffar — the Ever-Forgiving. Al-Tawwab — the One who constantly accepts repentance. Al-Wadud — the Loving. Al-Latif — the Subtly Kind. These are not just beautiful words. They are descriptions of reality. Of who Allah actually is.

A Closing Thought

If Shirk is the sin of giving Allah’s place to something else, then Yā’s is the sin of forgetting that His place exists at all. Both cut us off from our most fundamental need: a living, breathing relationship with our Creator.

You have not gone too far. You cannot go too far — not while you’re still alive and your heart still beats. The door is open. It has always been open. And the One on the other side of that door has been waiting, with more love and patience than you can imagine, for you to walk back through it.

So walk back through it.

“Surely Allah forgives all faults. Surely He is the Forgiving, the Merciful.”
