Salim narrates from his father: When he would start the prayer, he would raise his hands. When he would go into bowing (ruku‘), he would raise his hands. When he would say «سمع اللہ لمن حمدہ» (that is, when he would stand up from bowing), he would raise his hands. When he would stand up after two rak‘ahs, he would also raise both hands up to the shoulders.
