Explanation

Hazrat Umar (RA)  adopted the title of Ameer-ul-Momineen for the first time.

On his accession in 634, Umar ibn Khattab, the Second Rashidun Caliph, was given the title.

According to At-Tabaqat al Kubra, When Abu Bakr died, Muslims of the time said: “We are the Mu'minin and Umar is our Amir (Commander).”

After this, the title Amir al-Mu'minin was held by Umar ibn Khattab who was also the first one to be given this title.
