Wa’il b. Hujr said that he saw the Prophet (ﷺ) raise his hands when he began prayer. He said the <i>takbir</i>, 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 <i>takbir</i> 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. Muslim transmitted it.

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
