مسند أحمد

It was narrated that Sa`eed bin al-Musayyab said, `Uthman went for Hajj, and when he was halfway there, `Ali was informed that `Uthman had told his companions not to do tamattu`, `Ali said to his companions: When he sets out, set out too. `Ali and his companions entered ihram for ‘Umrah, and `Uthman did not say anything to them. `Ali said: Have I not been told that you have forbidden tamattu.” Didn`t the Messenger of Allah (ﷺ) do tamattu`? He (the narrator) said: I do not know what answer `Uthman (رضي الله عنه) gave.
