Musa b. 'Uqba is believed to be one of the earliest Maghazi chroniclers/authors. However, there is a great deal of controversy about his work, of which many people are unaware. Moreover, although many sources speak of this piece with praise, other sources neither mention its existence nor even accept its existence. A specific anthology was compiled for parts of this piece that the researchers were able to establish as legitimate. Additionally, along with the belief that this work was used until the end of 10th century after Hegira (XVth AD.), the researchers believe that the work still exists.
