Nafi' bin Jubayr bin Mut'im (may Allah have mercy on him) narrates from his father, Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him), who said: the Prophet (peace and blessings be upon him) said: "Walking on foot to the Friday prayers is an expiation for sins, as is performing ablution thoroughly in the cold, and waiting for the next prayer after the prayers."
