Musnad AhmedIt was narrated that Nubaih bin Wahb said:
Ibn Ma"mar wanted to marry his son to the daughter of Shaibah bin Jubair. So he sent me to Aban bin "Uthman who was the Ameer of Hajj. I came to him and said to him: Your brother wants to arrange his son"s marriage and wants you to witness it. He said: I think you are no more than an ill-mannered Iraqi. The pilgrim in ihram should not get married or arrange a marriage. Then he narrated a similar report from "Uthman (رضي الله عنه) and attributed it to the Prophet (ﷺ)
