"I saw the Messenger of Allah (ﷺ) raise his hands until they reached the highest part of his ears, when he said the takbir, when he bowed and when he raised his head from bowing
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ أَنْبَأَنَا إِسْمَاعِيلُ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ اللَّيْثِيِّ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَرْفَعُ يَدَيْهِ إِذَا كَبَّرَ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ حَتَّى بَلَغَتَا فُرُوعَ أُذُنَيْهِ ‏.‏
