Maliks Muwatta Book 20, Hadith Number 126.
Section : Tawaf in General.
Yahya related to me from Malik that he had heard that if Sad ibn Abi Waqqas entered Makka late, he would go to Arafa before doing tawaf of the House and say between Safa and Marwa, and then do tawaf when he got back.
Malik said, “The leeway is broad, if Allah wills.”
Malik was asked whether somebody that was doing obligatory tawaf could stop and talk with another man, and he said, “I do not like him to do that.”
Malik said, “Only someone who is pure (by being in wudu) should do tawaf of the House or say between Safa and Marwa.”
