I saw one reference that said that it translates to "abundance". It does show up, infrequently, in many different parts of the Arab world, so hard to say where it might have originated. Seems to be used, also, as a personal and regional name as far east as Bangladesh. The USDA/UC Davis website lists the origin as being from a couple people in the US, with no information about the provenance further back.
It also shows up in the European Minor Fruit Tree Project as being in a collection in Italy. I had heard it was from Egypt, but have no idea from whence I got that impression.
