Al-Tawba pillar or the pillar of Abu lubaba is one of the pillars of Masjid al-Nabi and the place of repentance of Abul Baba Ansari, a companion of the Prophet (PBUH), in the Battle of Bani Qurayzah. Feeling guilty for collaborating with the Jews of Bani Qurayzah, Abul Baba went to Masjid al-Nabi and tied himself to this pillar until his repentance was accepted. It is recommended to pray next to this pillar.
