It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that he said: If it was counted in a single gathering from the Messenger of Allah (peace and blessings be upon him) that he used to say: "O my Lord! Forgive me and accept my repentance. Surely, You are the Acceptor of repentance, the Most Forgiving." Then this would be counted a hundred times.
