(5) باب تَحْرِيمِ نِكَاحِ الْمُحْرِمِ وَكَرَاهَةِ خِطْبَتِهِ
Nubaih b. Wahb reported that 'Umar b. Ubaidullah intended to marry Talha b. 'Umar with the daughter of Shaiba b. Jubair; so he sent a messenger to Aban b. Uthman to attend the marriage, and he was at that time the Amir of Hajj. Aban said:
I heard 'Uthman b. 'Affan say that Allah's Messenger (ﷺ) had stated: A Muhrim must neither marry himself, nor arrange the marriage of another one, nor should he make the proposal of marriage.
