It was narrated that Abu Hurairah said:
“I saw the Messenger of Allah ﷺ raising his hands during prayer until they were parallel with his shoulders when he started to pray, when he bowed and when he prostrated.”

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَهِشَامُ بْنُ عَمَّارٍ، قَالاَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، عَنْ صَالِحِ بْنِ كَيْسَانَ، عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَرْفَعُ يَدَيْهِ فِي الصَّلاَةِ حَذْوَ مَنْكِبَيْهِ حِينَ يَفْتَتِحُ الصَّلاَةَ وَحِينَ يَرْكَعُ وَحِينَ يَسْجُدُ .
