Surah Al Mursalat Tafseer

Surely, what you are promised will occur.

This is the subject of these oaths.

This means, what you all have been promised concerning the establishment of the Hour (Judgement Day), the blowing of the horn, the resurrection of the bodies, the gathering of those of old and those of latter times on one common ground and the rewarding of every doer of a deed based upon his deed. If he did good, then his reward will be good, and if he did evil, then his reward will be evil. All of this will occur, meaning it will come to pass and there is no avoiding it.
