Sayyiduna Hudhayfah (may Allah be pleased with him) relates: I prayed with the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) began Surah al-Baqarah, and I said (to myself): He (peace and blessings be upon him) will recite it in one rak'ah. Then he (peace and blessings be upon him) kept on reciting. I said: He will bow with it. Then he (peace and blessings be upon him) began Surah al-Nisa' and recited all of it, then he began Surah Al Imran. He (peace and blessings be upon him) was reciting slowly and deliberately. Whenever he came to a verse containing glorification, he would say "Subhan Allah"; whenever he passed a verse of asking, he would ask; and whenever a verse of seeking refuge came, he would seek refuge. Then he (peace and blessings be upon him) bowed and in his bowing kept saying: 'Subhana rabbiya al-'azim' (Glory be to my Lord, the Magnificent). His (peace and blessings be upon him) bowing was about as long as his standing. Then he said: 'Sami' Allahu liman hamidah' (Allah has heard the one who praised Him), then he stood up for nearly as long as he had bowed, then he prostrated and kept saying: 'Subhana rabbiya al-a'la' (Glory be to my Lord, the Most High). His (peace and blessings be upon him) prostrations too were about as long as his standing.
