Musannaf Ibn Abi Shaybah 13085 — Reports on the reward of Hajj

Abdullah bin Amir bin Rabi'ah narrates from his father (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Keep performing Hajj and Umrah (keep them following one another), for both of them remove poverty and sins just as the furnace of fire removes the rust of iron."
