This is actually more the style of jinn and efreet bottled by Solomon. The three wishes stuff was more common with fairy magic (and spoiler, the wish maker would foul it up and get stuck with the consequences.)
With a djinn, it was more yeah, I'll do magic stuff for you until I get bored, and if you're very lucky, and don't piss me off too much, I just might let you live.
Think of a mafia don who owes you a favor and doesn't like the obligation hovering over him. And yet, if you ask for too much, he may just disappear you instead.
