What event preceded the arrival of Prophet Muhammad (saw) to Medina?
     Narrated 'Aisha:                          Allah caused the day of Buath to take place before Allah's Apostle was sent (as an Apostle) so that when Allah's Apostle reached Medina, those people had already divided (in different groups) and their chiefs had been killed or wounded. So Allah made that day precede Allah's Apostle so that they (i.e. the Ansar) might embrace Islam.
