The reciter: Qutaybah ibn Sa'id narrated to us: Hajjaj ibn Muhammad al-A'war narrated to us from Shu'bah from Amr ibn Murrah from Sa'id ibn al-Musayyib, who said:
`Ali and `Uthman differed regarding Hajj-at-Tamattu` while they were at 'Usfan (a familiar place near Mecca). `Ali said, "I see you want to forbid people to do a thing that the Prophet (ﷺ) did?" When `Ali saw that, he assumed Ihram for both Hajj and `Umra.
اختلف علي وعثمان رضي الله عنهما وهما بعسفان في المتعة فقال علي ما تريد إلا أن تنهى عن أمر فعله النبي صلى الله عليه وسلم فلما رأى ذلك علي أهل بهما جميعاً Sahih al-Bukhari 1569.
