Abu Huraira reported the Prophet as saying, “Seventy angels have been put in charge of it (i.e. the Yamani corner), so if anyone says, ‘O God, I ask Thee for pardon and wellbeing in this world and the next; our Lord, bring us a blessing in this world and a blessing in the next, and guard us from the punishment of hell’, they will say Amen.”
Ibn Majah transmitted it.
