It is narrated from Sayyiduna Malik bin al-Huwayrith (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) entered the prayer, he would raise both his hands to the tops of his ears, and he would do so also when he bowed and when he raised his head from bowing.
