It is narrated from Ibn Abi Mulaykah that Umar bin Khattab (may Allah be pleased with him) touched the Black Stone in order to perform Tawaf, then said: "Now, for whom should we expose our shoulders, and to whom should we show (our strength), when Allah has made Islam dominant? By Allah! I will perform Sa'i (Tawaf) in the same manner as they (i.e., the Prophet ﷺ) did."
