[Machine] The Prophet ﷺ used to say often: "Subhanaka Allahumma wa bihamdika Allahumma, ighfirli" which means "Glory be to You, O Allah, and praise be to You, O Allah, forgive me." When the verse was revealed: "When the victory of Allah and the conquest comes" (Quran 110:1), he said: "Subhanak Allahumma wa bihamdika Allahumma, ighfirli innaka anta at-tawwab" which means "Glory be to You, O Allah, and praise be to You, O Allah, forgive me, indeed You are the Acceptor of repentance."
