Sayyiduna Imran bin Husain (may Allah be pleased with him) narrated that (during Hajj) the command of Tamattu‘ was revealed in the Qur'an, and we performed Hajj with Tamattu‘ along with the Messenger of Allah (peace and blessings of Allah be upon him). Then after that, neither the Qur'an forbade it nor did the Prophet (peace and blessings of Allah be upon him) forbid it until he passed away. (Therefore, Tamattu‘ is still permissible.) It is only that a certain person has said whatever he wished based on his own opinion.
