Umar bin Ubaydullah sent word to Abban bin Uthman, who at that time was the leader of the pilgrims, while both of them were in a state of ihram, saying, "I intend to marry Talha bin Umar to the daughter of Shayba bin Jubayr, and I would like you to be present."Abban rejected this and said, "I heard Uthman bin Affan say that the Messenger of Allah ﷺ said, 'A person in a state of ihram may not marry, nor give anyone in marriage, nor make a proposal of marriage.'"
و حدثني عن مالك عن نافع
أن عمر بن عبيد الله أرسل إلى أبان بن عثمان وأبان يومئذ أمير الحاج وهما محرمان إني قد أردت أن أنكح طلحة بن عمر بنت شيبة بن جبير وأردت أن تحضر فأنكر ذلك عليه أبان وقال سمعت عثمان بن عفان يقول قال رسول الله ﷺ لا ينكح المحرم ولا ينكح ولا يخطب
