It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A servant commits a sin, then when he remembers it, he grieves over what he did; so when Allah Almighty looks at him and sees that he is grieved over what he did, He forgives him."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Muhammad bin Sirin (may Allah have mercy on him) except Salih al-Murri, and Dawud al-Muhabbar is alone in narrating it."
