(4) باب رَفْعِ الْيَدَيْنِ حِيَالَ الأُذُنَيْنِ
It was narrated from Malik bin Al-Huwairith- who was one of the companions of the Prophet (ﷺ)- that:
When the Messenger of Allah (ﷺ) prayed he would raise his hands-when he said the Takbir- until they were parallel to his ears, and when he wanted to bow and when he raised his head from bowing.
