Sunan an-Nasa'i 1069

It was narrated from Hudhaifah that:He prayed with the Messenger of Allah (ﷺ) one night and he heard him say when he said the takbir:

"Allahu Akbara dhal-jabaruti wal-malakuti wal-kibriya'i wal-'azamah (Allah is Most Great, the One Who has all power, sovereignty, magnificence and might.)" When bowing he would say: "Subhana Rabbial-'Azim (Glory be to my Lord Almighty)." When he raised his head from bowing he would say: "Lirabbil-hamd, Lirabbil-hamd (To my Lord be praise, to my Lord be praise)." And when he prostrated (he said): "Subhana Rabbial-A'la (Glory be to my Lord Most High)." And between the two prostrations (he said): "Rabbighfirli, Rabbighfirli (Lord forgive me, Lord forgive me)." His standing, his bowing, when he raised his head from bowing, his prostration and the time between the two prostrations, were almost the same
