The Messenger of Allah ﷺ said, "People, turn to Allah in repentance, for I myself repent to Him a hundred times each day."
قال رسول الله ﷺ: يا أيها الناس، توبوا إلى الله، فإني أتوب في اليوم إليه مائة مرة.
Muslim narrated it in the Book of Remembrance and Supplication (42:2702), from Abu Bakr bin Abu Shayba, who said, Ghundar narrated to us, from Shuba, from Amr bin Mura, from Abu Burda, who said, I heard Aghar, who was one of the companions of the Prophet ﷺ, narrating from Ibn Umar, who said, and he mentioned it.
