So how many other jinn did Allah create? Whenever we talk about hell it's never plural.
Hell
Shaytan
Devil
Iblis
Jinn
There is no plural there. Or is there more than one shaytan?
I don't understand what you're asking. But:
"Shaytan" refers to someone that is pre-disposed to evil
So by that definition, Iblis is a Shaytan
Devil is an English word that is synonymous with Shaytan
Jinn is the race of beings that Iblis belongs to
Before Allah created Adam (pbuh), there were jinn roaming this planet. There were evil jinn among them who were making trouble so Allah sent Iblis to take care of them.
Iblis has children and descendants that are alive till this day.
He was punished due to his arrogance in not bowing to Adam but has been granted respite till the day of judgement when he will be thrown forever into hell.
Till then, he has taken it upon himself to misguide people from the race of Adam.
