Derivation of this name orignally comes from a imitation of (Qassim) that is the pet name of prophet mohd alaihissalam is addressed as Abul Qasim, and it is unique for him alone that is not desirable to address other than him as Abul Qasim, people later on began to tilt the letter (Q) to letter (J). and is widely used as an arabic term. and the further definition, allah knows.
