‘Alqama said that Ibn Mas'ud suggested leading them in prayer in the way God’s Messenger had performed it. He prayed, raising his hands only once, along with the takbir at the beginning.
Tirmidhi, Abu Dawud and Nasa’i transmitted it, and Abu Dawud said it is not sahih put this way.
‘Ali b. al-Husain told in mursal form that God’s Messenger said the takbir in prayer as often as he got down1 and got up2 and that this continued to be his method in prayer till he met God.
1. i.e. for bowing or prostration.
2. i.e. after prostration.
I prayed behind an old man in Mecca and he said the takbir twenty-two times. When I said to Ibn ‘Abbas that the man was a fool, he replied, “I am surprised at you. It was the sunna of Abul Qasim.’’*
