Sahih Muslim 401
Wa'il b. Hujr reported:
He saw the Messenger of Allah (ﷺ) raising his hands at the time of beginning the prayer and reciting takbir, and according to Hammam (the narrator), the hands were lifted opposite to ears. He (the Holy Prophet) then wrapped his hands in his cloth and placed his right hand over his left hand. And when he was about to bow down, he brought out his hands from the cloth, and then lifted them, and then recited takbir and bowed down, and when (he came back to the erect position) he recited:" Allah listened to him who praised Him." And when he prostrated, he prostrated between his two palms.
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 ‏.‏
