Nafi‘ said that when Ibn ‘Umar began prayer he said the takbir and raised his hands; when he bowed he raised his hands; when he said, “God listens to him who praises Him” he raised his hands; and when he got up at the end of two rak'as he raised his hands. Ibn ‘Umar traced that back to the Prophet.
Ibn ‘Umar said that God’s Messenger used to raise his hands opposite his shoulders when he began prayer and when he said the takbir before bowing; and when he raised his head after bowing he raised them in the same way and said, “God listens to him who praises Him. To Thee, our Lord, be the praise!” But he did not do that when he prostrated himself.
Malik b. al-Huwairith said that when God’s Messenger said the takbir he raised his hands and placed them opposite his ears, and when he raised his head after bowing and said, “God listens to him who praises Him,” he did the same. A version has, “and placed them opposite the tops of his ears.”
Abu Humaid as-Sa'idi said among a company of the companions of God’s Messenger, “I am the one among you who is best versed in the way God’s Messenger prayed. I saw that when he uttered the takbir he placed his hands opposite his shoulders; when he bowed he rested his hands on his knees, then bent his back; when he raised his head he stood erect with his spine straight; when he prostrated himself he placed his arms so that they were not spread out, and the fingers were not drawn in, and the points of his toes were facing the qibla; when he sat up at the end of two rak'as he sat on his left foot and raised the right; and when he sat up after the last rak'a he put forward the left foot, raised the other, and sat on his hips.”
