(1) باب نَسْخِ ذَلِكَ
It was narrated that Mus'ab bin Sa'd said:
"I prayed beside my father and I put my hands between my knees, and he told me: 'Put your hands on your knees.' Then I did that again and he struck my hands and said: 'We were forbidden to do that, and we were commanded to put our hands on our knees.'"
