Sayyiduna Yahya bin Adam Sululi, may Allah be pleased with him, who was present at the occasion of the Farewell Pilgrimage, narrates that the Messenger of Allah, peace and blessings be upon him, said: "Ali is from me and I am from Ali. On my behalf, either I will fulfill (the obligation) myself, or Ali will fulfill it." The wording of Ibn Abi Bakir's narration is: "I will pay my debt myself or Ali will pay it on my behalf."
