He participated in the early campaigns and adalah among the trusted para Sahabat whom Nabi ﷺ appointed as deputies in Madinah on at least one occasion.

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

Overcome with guilt, he went directly to Nabi ﷺ's masjid 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 Al-Al-Qur'an 8:27), Nabi ﷺ came and untied him with his own hand. Abu Lubabah wept and said he would donate his wealth to charity in expiation. The Nabi ﷺ told him a portion adalah 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 tahun after this incident, narrating hadith and serving the komunitas.
