Abu Lubabah's Slip, Repentance, and the Pillar of Tawbah

Shaykh Yasir Qadhi explains:

Late in the siege, Banū Qurayẓah asked specifically for Abū Lubābah, an Anṣārī of the Aws who, from the tribe's pre-Islamic alliance with the Aws, had been a close personal friend of theirs for years, visiting their fortress and sharing meals with them long before Islam. The Prophet ﷺ permitted him to go. Surrounded by the tribe's frightened women and children, who begged him as though he held the power to decide their fate, Abū Lubābah's old affection for them overcame him. Asked whether they should surrender, he answered yes, but made an unauthorized gesture across his throat, signaling that surrender would still mean execution, a signal the Prophet ﷺ had never actually confirmed to him.

Abū Lubābah later said that before his feet had even moved from that spot, he understood he had betrayed Allah and His Messenger ﷺ, not necessarily by revealing false information, but by showing sympathy toward the enemy at a moment that demanded undivided loyalty (walāʾ). Overwhelmed with guilt, he bypassed both the army and the Prophet ﷺ entirely, went straight to the mosque, and tied himself to one of its pillars, vowing not to leave until Allah accepted his repentance, and never to set foot near Banū Qurayẓah again, unwilling to remain in a place where he had disobeyed Allah and His Messenger ﷺ.

When the Prophet ﷺ eventually learned what had happened, he said that had Abū Lubābah come to him directly he would have asked Allah's forgiveness on his behalf, but now that he had bound himself by his own vow (nadhr), nothing could be done except to let the vow run its course, since the Qur'ān commands the fulfillment of vows. Abū Lubābah remained tied to the pillar for well over a week. One morning before Fajr, the Prophet ﷺ was found laughing; when Umm Salamah asked why, he told her Allah had accepted Abū Lubābah's repentance. She asked permission to go tell him herself, her quarters at the time still had direct access to the mosque, before this access was later restricted to ʿĀ'ishah's alone, and ran to deliver the news. Even then, Abū Lubābah refused to be untied by anyone but the Prophet ﷺ himself, wanting certainty that his repentance was complete; the Prophet ﷺ came before Fajr prayer and untied him with his own hands.

Two Qur'ānic verses are associated with this episode: Sūrat al-Anfāl 8:27, warning believers against betraying the trust of Allah, His Messenger ﷺ, and their own responsibilities knowingly (يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَخُونُوا اللَّهَ وَالرَّسُولَ وَتَخُونُوا أَمَانَاتِكُمْ وَأَنْتُمْ تَعْلَمُونَ); and Sūrat al-Tawbah 9:102, describing "others who have confessed their sins, having mixed a righteous deed with another that was bad, that Allah may turn to them in forgiveness" (وَآخَرُونَ اعْتَرَفُوا بِذُنُوبِهِمْ خَلَطُوا عَمَلًا صَالِحًا وَآخَرَ سَيِّئًا عَسَى اللَّهُ أَنْ يَتُوبَ عَلَيْهِمْ). Ḥasan al-Baṣrī called this verse the most hope-giving in the entire Qur'ān, since it describes believers whose record contains both good and bad rather than perfection, offered the hope that Allah's forgiveness may still reach them.
