‘Urwa b. az-Zubair said: The Prophet has performed the hajj , and ‘A’isha told me that the first thing he did when he came to Mecca was to perform ablution, then go round the House, but an ‘umra was not observed. Then Abu Bakr performed the hajj and the first thing he did was to go round the House, but an ‘umra was not observed. Then ‘Umar and afterwards ‘Uthman did similarly. Bukhari and Muslim.
