Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Perform Hajj and Umrah one after the other, for the two of them remove sins just as the furnace removes the dross (that is, the rust) of iron."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Kabir; its chain contains a narrator, Hajjaj bin Nusayr, whom Ibn Hibban and others declared thiqah (trustworthy), while Imam al-Nasa'i (may Allah have mercy on him) and others called him da'if (weak).
