Abu Bakr had initially engaged his daughter ʽAʼisha to Muṭʽim's son Jubayr ibn Muṭʽim some time between her birth in 613 and 619. When Muṭʽim was informed that Abu Bakr had adopted Islam, he no longer wished his son to marry ‘A’isha, who later married Muhammed.

All of your affair before today was bearable, until what you said today. I bear witness that you are a liar. We strike the flanks of the she-camels for one month to reach the Hallowed House, then for another month to come back, and you claim that you went there in one night! By Allat, by al-‘Uzzá! I do not believe you.[2]

Saʽd ibn ʽUbadah participated in the secret Second pledged.
