Abu Lubabah al-Ansari

Abu Lubabah Bashir ibn Abd al-Mundhir al-Ansari (died ca. 30 AH) was a Companion of the Prophet ﷺ from the Aws tribe of Medina, remembered primarily for a moment of grave error and extraordinary repentance. He participated in the early campaigns and was among the trusted Companions whom the Prophet ﷺ appointed as deputies in Medina on at least one occasion.

During the siege of the Banu Qurayza tribe in 5 AH, who had broken their treaty with the Muslims, the besieged Jews sent for Abu Lubabah, who was their ally, to advise them. When they asked him what would happen if they submitted to the Prophet's judgment, he instinctively drew his hand across his throat — indicating they would be killed. He immediately realized he had betrayed the Prophet ﷺ by revealing information about his intentions.

Overcome with guilt, he went directly to the Prophet's mosque and tied himself to one of the pillars, vowing not to untie himself until Allah accepted his repentance. He remained tied for many days, refusing food and water beyond the minimum. When revelation came confirming his repentance (interpreted as Quran 8:27), the Prophet ﷺ came and untied him with his own hand. Abu Lubabah wept and said he would donate his wealth to charity in expiation. The Prophet ﷺ told him a portion was sufficient.

His story became a famous example of sincere repentance, self-imposed hardship in remorse, and divine forgiveness — themes central to Islamic spiritual life. He lived for years after this incident, narrating hadith and serving the community.
