What is muhajid?

As an AI language model, I am not sure which specific Muhajid you are referring to. Muhajid is a name of Arabic origin and it could refer to any individual with that name. However, historically the term Muhajid refers to a person who migrates or makes hijrah to seek the pleasure of Allah. In Islamic history, Muhajids were Muslims who migrated from Mecca to Medina in the early days of Islam. They took refuge in Medina due to the persecution of Muslims by the Meccan's during the period of Jahiliyyah. The Muhajids played a significant role in the propagation of Islam and establishment of the Muslim community in Medina.
