A man from (the tribe of) 'Abs narrated from Hudhaifah that:
He came to the Prophet ﷺ and stood by his side, and he said: "Allahu Akbar Dhul-malakut wal-jabarut wal-kibriya' wal 'azamah (Allah is Most Great, the One Who has all sovereignty, power, magnificence, and might.)" Then he recited Al-Baqarah, then he bowed, and his bowing lasted almost as long as his standing, and he said when bowing: 'Subahana Rabbial-'azim, Subhana Rabbial-'azim (Glory be to my Lord Almighty, Glory be to my Lord Almighty)." When he raised his head he said: "Li Rabbial-hamd, Li Rabbial-hamd (To my Lord be praise, to my Lord be praise)." And when he prostrated he said: "Subahana Rabbial-A'la, Subahna Rabbial-A'la (Glory be to my Lord Most High, glory be to my Lord Most High)." And between the two prostrations he would say: "Rabbighfirli, Rabbighfirli (Lord forgive me, Lord forgive me)."
