It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) heard a man saying the talbiyah on behalf of Shubrumah, so he asked: "Who is Shubrumah?" He said: My brother, or a relative of mine. He (peace and blessings be upon him) asked: "Have you ever performed Hajj?" He said: No. He (peace and blessings be upon him) said: "Then make this Hajj for yourself, then perform it on his behalf afterwards."
Ghundar narrated it from Sa'id bin Abi Arubah as mawquf (stopping at Ibn Abbas), but the one who narrated it marfu' (attributed to the Prophet) is a reliable hafiz, so the disagreement of whoever contradicted him does not harm it.
