Tafsir of Ya seen 36:63

(This is Hell which you were promised)

This is an initiation of speech addressed to them after the completion of the rebuking, chiding, binding, and silencing, at the moment they overlook the brink of Hell. That is: "This, which you see, is the Hell that you never ceased being promised would be your entry-place, through the tongues of the Messengers (peace be upon them) and those conveying from them, in exchange for your worship of Satan."
