Sa'id bin al-Musayyab reported that 'Ali and 'Uthman (RA) met at 'Usfan; and 'Uthman used to forbid (people) from performing Tamattu' and 'Umrah (during the period of Hajj), whereupon 'Ali said: What is your opinion about a matter which the Messenger of Allah ( صلی اللہ علیہ وسلم ) did, but you forbid it? Thereupon 'Uthman said: You leave us alone, whereupon he ('Ali) said: I cannot leave you alone. When 'Ali saw this, he put on Ihram for both of them together (both for Hajj and 'Umrah).
