Tafsir of Ad-Dukhan 44:15

Verily, We shall remove the torment for a while. Verily, you will revert. means, `if We were to remove the torment from you for a while, and send you back to the world, you would go back to your former state of disbelief and denial.' This is like the Ayat:

ولو رحمنهم وكشفنا ما بهم من ضر للجوا فى طغينهم يعمهون

And though We had mercy on them and removed the distress which is on them, still they would obstinately persist in their transgression, wandering blindly. (23:75)

ولو ردوا لعدوا لما نهوا عنه وإنهم لكذبون

But if they were returned (to the world), they would certainly revert to that which they were forbidden. And indeed they are liars! (6:28) The Meaning of the "Great Batshah''

يوم نبطش البطشة الكبرى إنا منتقمون
