(9)
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 ‏.‏

Sahih Muslim 391 b

Malik b. Huwairith reported:

The Messenger of Allah (ﷺ) raised his hands apposite his ears at the time of reciting the takbir (i. e. at the time of beginning the prayer) and then again raised his hands apposite the ears at the time of bowing and when he lifted his head after bowing he said: Allah listened to him who praised Him, and did like it (raised his hands up to the ears).
حَدَّثَنِي أَبُو كَامِلٍ الْجَحْدَرِيُّ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا كَبَّرَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا أُذُنَيْهِ وَإِذَا رَكَعَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا أُذُنَيْهِ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَقَالَ ‏ "‏ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ ‏"‏ ‏.‏ فَعَلَ مِثْلَ ذَلِكَ ‏.‏
