Bismillah
As Salam alaikum
3lameen- translated as "worlds" but means "all of creation" or "all Created things."
One of the problems with english version.
Maybe this will help.

It only really touches on the topics of demons but in the full book as translated by Abu Ameenah Phillips it discusses the alien/jinn connection.
Insha'Allah it will help.
As Salam alaikum wa rahmatullahi wa barakatu
