I believe he was misinformed by some somalis who don't know af Somali very well. Magan is a name in the sense of " protector" or the one who can give refuge,Magan: 1. Badbaadinta la siiyo cid tabar darran. 2. Qof tabar darran oo qof kale ku tiirsan si uu badbaado u helo.
Magan: 1. The protection given to the weaker. 2. A weak person dependent on another person to be safe.
Sounds like refugee, maybe not directly, but indirectly.
