´It was narrated from Abdullah bin Ubaid bin Umair that a man said:` "O Abu abdur-Rahman, why do I only see you touching these two corners?" He said: "I heard the Messenger of Allah say: 'Touching them erases sins.' And I head him say: 'whoever circumambulates seven times, it is like freeing a slave.'"
