"I saw the Messenger of Allah ﷺ, when he started to pray, raise his hands, and when he bowed, and when he raised his head from bowing, until they were parallel with the top of his ears." (Using translation from Nasāʾī 881)
رَأَيْتُ رَسُولَ اللهِ ﷺ إِذَا دَخَلَ فِي الصَّلَاةِ رَفَعَ يَدَيْهِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ حَتَّى حَاذَتَا فُرُوعَ أُذُنَيْهِ
