It is narrated from Nabiya bin Wahb that Umar bin Ubaidullah intended to marry Talha bin Umar to the daughter of Shaibah bin Jubair, so he sent a message to Aban bin Uthman to participate (in the marriage), and both (the ones to be married) were in the state of ihram. Aban refused to participate and said: I heard Uthman bin Affan (may Allah be pleased with him) say that the Messenger of Allah (ﷺ) said: "Neither should a person in ihram marry, nor arrange a marriage, nor propose."
