(76) باب مَا جَاءَ فِي رَفْعِ الْيَدَيْنِ عِنْدَ الرُّكُوعِ
Salim narrated from :
his father (Ibn Umar) who said: "I saw Allah's Messenger when he opened the Salat, raising his hands to the level of his shoulders, and (again) when he bowed, and when he raised his head from bowing." In his narration, Ibn Abi Umar added: "And he wuld not raise them between the two prostrations."
