باب اسْتِحْبَابِ رَفْعِ الْيَدَيْنِ حَذْوَ الْمَنْكِبَيْنِ مَعَ تَكْبِيرَةِ الإِحْرَامِ وَالرُّكُوعِ وَفِي الرَّفْعِ مِنَ الرُّكُوعِ وَأَنَّهُ لاَ يَفْعَلُهُ إِذَا رَفَعَ مِنَ السُّجُودِ
Sahih Muslim 391 a

Abu Qilaba reported that he saw Malik b. Huwairith raising his hands at the beginning of prayer and raising his hands before kneeling down, and raising his hands after lifting his head from the state of kneeling, and he narrated that the Messenger of Allah (ﷺ) used to do like this.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ، عَنْ خَالِدٍ، عَنْ أَبِي قِلاَبَةَ، أَنَّهُ رَأَى مَالِكَ بْنَ الْحُوَيْرِثِ إِذَا صَلَّى كَبَّرَ ثُمَّ رَفَعَ يَدَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ رَفَعَ يَدَيْهِ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ رَفَعَ يَدَيْهِ وَحَدَّثَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَفْعَلُ هَكَذَا ‏.‏
