When did the first pledge of Al -Aqabah take place?

The first pledge of Al-Aqabah took place in the year 621 CE, during the Islamic month of Dhul-Hijjah. This event marked a significant moment in the early Islamic community, as a group of twelve representatives from the tribes of Khazraj and Aws pledged their allegiance to the Prophet Muhammad, committing to support and protect him and his followers. This pledge set the stage for the later migration (Hijrah) to Medina and the establishment of the Muslim community there.
