How did Allah's Apostle (peace be upon him) advise Um Salama to perform the Tawaf of the Ka`ba while the people were in prayer?
 Narrated Um Salama:                     (the wife of the Prophet) I informed Allah's Apostle (about my illness). (Through other sub-narrators, Um Salama narrated that when Allah's Apostle was at Mecca and had just decided to leave (Mecca) while she had not yet done Tawaf of the Ka`ba (and after listening to her). The Prophet said, "When the morning prayer is established, perform the Tawaf on your camel while the people are in prayer." So she did the same and did not offer the two rak`at of Tawaf until she came out of the Mosque.
