Qasim bin Muhammad showed them how to sit during the tashahhud. He set his right foot upright, folded his left leg beneath him, and sat on his left hip rather than on his foot. Then he said, "Abdullah bin Abdullah bin Umar showed me this, and he told me that his father used to do it this way."
و حدثني يحيى عن مالك
