What he said with his face on the ground
Hudhayfah stood at his side and recorded every position.
سُبْحَانَ رَبِّيَ الأَعْلَى سُبْحَانَ رَبِّيَ الأَعْلَى
Subḥāna rabbiya-l-aʿlā
“Glory to my Lord, the Most High.”
Where this comes from
Hudhayfah lists it all in order. The opening takbir with four names, al-Baqarah, a bowing as long as the standing, then the rising, then this in the prostration. The lowest posture takes the highest name.
The full narration
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)
