(9)
باب اسْتِحْبَابِ رَفْعِ الْيَدَيْنِ حَذْوَ الْمَنْكِبَيْنِ مَعَ تَكْبِيرَةِ الإِحْرَامِ وَالرُّكُوعِ وَفِي الرَّفْعِ مِنَ الرُّكُوعِ وَأَنَّهُ لاَ يَفْعَلُهُ إِذَا رَفَعَ مِنَ السُّجُودِ
Sahih Muslim 390 b

Ibn Umar reported that the Messenger of Allah (ﷺ), when he stood up for prayer, used to raise his hands apposite the shoulders and then recited takbir (Allah-o-Akbar), and when he was about to bow he again did like it and when he raised himself from the ruku' (bowing posture) he again did like it, but he did not do it at the time of raising his head from prostration.

حَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، حَدَّثَنِي ابْنُ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، أَنَّ ابْنَ عُمَرَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا قَامَ لِلصَّلاَةِ رَفَعَ يَدَيْهِ حَتَّى تَكُونَا حَذْوَ مَنْكِبَيْهِ ثُمَّ كَبَّرَ فَإِذَا أَرَادَ أَنْ يَرْكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَلاَ يَفْعَلُهُ حِينَ يَرْفَعُ رَأْسَهُ مِنَ السُّجُودِ ‏.‏
