Yahya related to me from Malik that he had heard that if Sad ibnAbi Waqqas entered Makka late, he would go to Arafa before doing tawafof the House and say between Safa and Marwa, and then do tawaf when hegot back.Malik said, "The leeway is broad, if Allah wills."Malik was asked whether somebody that was doing obligatorytawaf could stop and talk with another man, and he said, "I do notlike him to do that."Malik said, "Only someone who is pure(by being in wudu) should do tawaf of the House or say between Safaand Marwa."
