Hadith 687:15
Waki’ narrated to us, from al-Mas’udi, from ‘Abd al-Jabbar ibn Wa’il, who said: The people of my household narrated to me, from my father, "that he saw the Prophet, peace and blessings of Allah be upon him, raising his hands with the takbir, and placing his right hand upon his left in the prayer."
حدثنا وكيع، عن المسعودي، عن عبد الجبار بن وائل، حدثني أهل بيتي، عن أبي، " أنه رأى النبي صلى الله عليه وسلم يرفع يديه مع التكبيرة، ويضع يمينه على يساره في الصلاة "
