Abu Bakr married twice, and fathered four children, before the beginning of the Revelation (i.e. at least 13 years before the Hijrah): 'Abdullah, Asma, 'Abdur-Rahman, and 'A'isha. This is uncontested and well-known to the Muslims. 'A'isha was betrothed to Jubayr ibn Mut'im ibn Adi, before Abu Bakr accepted Islam in the first year of the Call (12-13 years before the Hijrah). This is uncontested. When Abu Bakr planned to go to Abyssinia during the fifth year of the Call (8-9 years before the Hijrah), Mut'im broke off the engagement because Abu Bakr had accepted Islam. This is uncontested.
