Sunan Abi Dawud 21363
In-book no 859حَدَّثَنَا وَهْبُ بْنُ بَقِيَّةَ، عَنْ خَالِدٍ، عَنْ مُحَمَّدٍ، - يَعْنِي ابْنَ عَمْرٍو - عَنْ عَلِيِّ بْنِ يَحْيَى بْنِ خَلاَّدٍ، عَنْ أَبِيهِ، عَنْ رِفَاعَةَ بْنِ رَافِعٍ، بِهَذِهِ الْقِصَّةِ قَالَ " إِذَا قُمْتَ فَتَوَجَّهْتَ إِلَى الْقِبْلَةِ فَكَبِّرْ ثُمَّ اقْرَأْ بِأُمِّ الْقُرْآنِ وَبِمَا شَاءَ اللَّهُ أَنْ تَقْرَأَ وَإِذَا رَكَعْتَ فَضَعْ رَاحَتَيْكَ عَلَى رُكْبَتَيْكَ وَامْدُدْ ظَهْرَكَ " . وَقَالَ " إِذَا سَجَدْتَ فَمَكِّنْ لِسُجُودِكَ فَإِذَا رَفَعْتَ فَاقْعُدْ عَلَى فَخِذِكَ الْيُسْرَى " .
This tradition has also been transmitted through a different chain of narrators by Rifa’ah b. Rafi. This version goes: When you get up and face the qiblah, what Allah wishes you to recite. And when you bow, put your palms on your knees and stretch out your back. When you prostrate yourself, do it completely( so that you are at the rest). When you raise yourself then sit on your left thigh.
