حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلميَرْفَعُ يَدَيْهِ إِذَا كَبَّرَ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ حَتَّى يَبْلُغَ بِهِمَا فُرُوعَ أُذُنَيْهِ ‏.‏
Translation
Malik b. al-Huwairith said

I saw the Prophet (ﷺ) raising his hands when he pronounced the takbir, when he bowed, and when he raised his head from bowing, until he brought them to the level of the lobes of his ears.
