يَرْفَعُ يَدَيْهِ إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ "
It was narrated from Malik bin Al-Huwairith that: He saw the Prophet (ﷺ) raise his hands when he bowed, and when he raised his head from bowing, until they were in level with the highest part of his ears.
