Amatul Rahman Omar
Truly, We revealed this (Book) in a Night full of blessings (Lailatul Qadr, as) it has been Our wont to warn (people against evil).
Hilali & Khan
We sent it (this Quran) down on a blessed night [(i.e. night of Qadr, Surah No: 97) in the month of Ramadan,, the 9th month of the Islamic calendar]. Verily, We are ever warning [mankind that Our Torment will reach those who disbelieve in Our Oneness of Lordship and in Our Oneness of worship].
