How did the muhajirun and ansar differ in early Muslim society?

In early Muslim society, the distinction between the muhajirun and the ansar was defined by their origins and their roles in supporting the Prophet Muhammad following his migration from Mecca to Medina in 622 CE.12

• The Muhajirun (Emigrants): This group consisted of Muhammad’s followers who emigrated with him from Mecca to Medina to escape persecution. They were highly esteemed for their early conversion to Islam (sabiqah) and the hardships they endured in Mecca. In the Qur'an, they are described as having a higher status before God. Following Muhammad's death, the muhajirun assumed leadership of the Muslim polity through the caliphate.12
• The Ansar (Helpers): This group comprised the local residents of Medina who aided Muhammad and the muhajirun. They belonged to the two major Medinese tribes, the al-Khazraj and the al-Aws, whom Muhammad had reconciled. The ansar were devoted supporters who made up the majority of the Muslim army at the Battle of Badr. However, after no one from their ranks was chosen as caliph, their influence as a distinct group declined, and they eventually merged into the broader Muslim community.12
