Narrated AbuHurayrah:

When the Messenger of Allah ﷺ uttered the takbir (Allah is most great) for prayer (in the beginning), he raised his hands opposite to his shoulders; and when he bowed, he did like that; and when he raised his head to prostrate, he did like that; and when he got up at the end of two rak'ahs, he did like that.

حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ، حَدَّثَنِي أَبِي، عَنْ جَدِّي، عَنْ يَحْيَى بْنِ أَيُّوبَ، عَنْ عَبْدِ الْمَلِكِ بْنِ عَبْدِ الْعَزِيزِ بْنِ جُرَيْجٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ بْنِ هِشَامٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ قَالَ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا كَبَّرَ لِلصَّلاَةِ جَعَلَ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ لِلسُّجُودِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا قَامَ مِنَ الرَّكْعَتَيْنِ فَعَلَ مِثْلَ ذَلِكَ .
