He said that he saw the Prophet praying, and when he had prayed an odd number of rak'as he did not stand up till after he had adopted a sitting position.
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.”
وَعَن وَائِل بن حجرأنه رأى النَّبِي صلى الله عَلَيْهِ وَسلم رفع يَدَيْهِ حِينَ دَخَلَ فِي الصَّلَاةِ كَبَّرَ ثُمَّ الْتَحَفَ بِثَوْبِهِ ثُمَّ وَضَعَ يَدَهُ الْيُمْنَى عَلَى الْيُسْرَى فَلَمَّا أَرَادَ أَنْ يَرْكَعَ أَخْرَجَ يَدَيْهِ من الثَّوْب ثمَّ رفعهما ثمَّ كبر فَرَكَعَ فَلَمَّا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ رَفَعَ يَدَيْهِ فَلَمَّا سَجَدَ سَجَدَ بَيْنَ كَفَّيْهِ. رَوَاهُ مُسلم
Wa’il b. Hujr said that he saw the Prophet raise his hands when he began prayer. He said the takbir, then pulled his garment round him, then placed his right hand on his left. When he was about to bow he took his hands out of his garment, and after he had raised (them and said the takbir he bowed. When he said, “God listens to him who praises Him” he raised his hands, and when he prostrated himself he did it between his hands.
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.
