Saeed bin Musayyib narrates: Sayyiduna Ali and Sayyiduna Uthman (may Allah be pleased with them) both came for Hajj. On the way, Sayyiduna Uthman forbade combining Umrah with Hajj as Tamattu’. Sayyiduna Ali (may Allah be pleased with him) was informed that Sayyiduna Uthman (may Allah be pleased with him) had prohibited Hajj Tamattu’, so Sayyiduna Ali (may Allah be pleased with him) said:“When you see that he has departed, then you also depart.”Then Sayyiduna Ali (may Allah be pleased with him) and his companions began reciting the Talbiyah for Umrah, but Sayyiduna Uthman did not stop them. Sayyiduna Ali (may Allah be pleased with him) said:“I have come to know that you have prohibited combining Umrah as Tamattu’.”So he replied:“Yes!”Then Sayyiduna Ali said to him:“Did you not hear that the Noble Prophet (peace and blessings be upon him) performed Tamattu’?”He replied:“Yes.”
