I saw "Ali and "Uthman (رضي الله عنهما) between Makkah and Madinah. "Uthman was telling people not to do tamattu" or join them together (Hajj and ‘Umrah, i.e., qiran). When "Ali (رضي الله عنه) saw that, he entered ihram for both of them together and said: Here I am for "Umrah and Hajj together ‘Uthman (رضي الله عنه) said: You see me telling the people not to do that and you do it? He said: I will not give up a Sunnah of the Messenger of Allah (ﷺ) for the opinion of anyone among the people.
