حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا مُحَمَّدُ بْنُ جُحَادَةَ، حَدَّثَنِي عَبْدُ الْجَبَّارِ بْنُ وَائِلٍ، عَنْ عَلْقَمَةَ بْنِ وَائِلٍ، وَمَوْلًى، لَهُمْ أَنَّهُمَا حَدَّثَاهُ عَنْ أَبِيهِ، وَائِلِ بْنِ حُجْرٍ، أَنَّهُ رَأَى النَّبِيَّ صلى الله عليه وسلم رَفَعَ يَدَيْهِ حِينَ دَخَلَ فِي الصَّلاَةِ كَبَّرَ - وَصَفَ هَمَّامٌ حِيَالَ أُذُنَيْهِ - ثُمَّ الْتَحَفَ بِثَوْبِهِ ثُمَّ وَضَعَ يَدَهُ الْيُمْنَى عَلَى الْيُسْرَى فَلَمَّا أَرَادَ أَنْ يَرْكَعَ أَخْرَجَ يَدَيْهِ مِنَ الثَّوْبِ ثُمَّ رَفَعَهُمَا ثُمَّ كَبَّرَ فَرَكَعَ فَلَمَّا قَالَ " سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ " . رَفَعَ يَدَيْهِ فَلَمَّا سَجَدَ سَجَدَ بَيْنَ كَفَّيْهِ .
Wail ibn Hujr reported that he saw the Prophet ﷺ raise his hands when beginning prayer and say Allahu Akbar. Hammam described them as level with his ears. The Prophet ﷺ then wrapped his garment around himself and placed his right hand over his left. When he was about to bow, he brought his hands out from beneath the garment, raised them, said Allahu Akbar, and bowed. When he said Allah hears whoever praises Him, he raised his hands. When he prostrated, he prostrated between his palms.
