Sa'id al-Maqburi said, "I passed by Ibn 'Umar who had a man with him with whom he was conversing. I went to them, and he struck me on the chest and said, 'When you find two men conversing, do not go up to them nor sit with them until they give you permission.' I said. 'May Allah make you prosper, Abu 'Abdu'r-Rahman. I hoped that I would hear something good from you.'"
