Volume 5, Book 58, Number 267:
Narrated ‘Aisha:
The day of Bu’ath was a day (i.e. battle) which Allah caused to take place just before the mission of
His Apostle so that when Allah’s Apostle came to Medina, they (the tribes) had divided (into hostile
groups) and their nobles had been killed; and all that facilitated their conversion to Islam.
