Abu Huraira said that when God’s Messenger got up to pray he would say the takbir when standing, then say the takbir when bowing, then say, “God listens to him who praises Him” when coming to an erect position after bowing, then say while standing, “To Thee, our Lord, be the praise,” then say the takbir when getting down for prostration, then say the takbir when he raised his head, then say the takbir when he prostrated himself, then say the takbir when he raised his head. He would do that throughout the whole prayer till he finished it, and he would say the takbir when he got up at the end of two rak'as after adopting the sitting posture.
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.
