First Pledge of Aqabah

During the Hajj season, twelve men from Yathrib (Medina) met the Prophet ﷺ at Aqabah near Mina and pledged allegiance, known as Bay'at al-Aqabah al-Ula. They pledged not to associate partners with Allah, not to steal, not to commit unlawful sexual intercourse, not to kill their children, and to obey the Prophet in good. This pledge, also called Bay'at al-Nisa (Pledge of Women) as it contained no military clauses, opened the door for Islam to spread in Medina.
