Narrated to us ['Affan] had told us [Syu'bah] from [Abu Ishaq] he said : I heard [Abu Ubaidah] from [his father] he said : The Prophet peace be upon him often said: "Glory be to You, O Allah, by praising You, O Allah, forgive me." When the verse was revealed: (When Allah's help and victory have come), he said: "Glory are You O Allah, and by praising You forgive me, verily You are Most Accepting of repentance.
