مسند أحمد

It was narrated that Ya`la bin Umayyah said: I circumambulated (the Ka’bah] with `Umar bin al-Khattab (رضي الله عنه) and he touched the corner, Ya`la said: I was next to the House and when I reached the western corner which is next to the Black Stone, I took his hand to touch it and he said: What is the matter with you? I said. Aren`t you going to touch it? He said: Did you not do tawaf with the Messenger of Allah (ﷺ) ? I said: Yes indeed. He said: Did you see him touch these two western corners? I said: No. He said: Don`t you have a good example in him? I said: Yes indeed. He said: Then stop bothering about that.
