Ja'far ibn Bashir narrated from Al-'Ala', from Muhammad ibn Muslim, from Abu Ja'far عليه السلام, who said: I asked him about a man who performs Hajj on behalf of his father. Should he perform Tamattu‘ (Umrah and Hajj combined)? Imam عليه السلام said: "Yes, the Tamattu‘ is for him, and the Hajj is on behalf of his father."
