15:8

مَا نُنَزِّلُ الْمَلَائِكَةَ إِلَّا بِالْحَقِّ وَمَا كَانُوا إِذًا مُّنظَرِينَ

Transliteration:

Ma nunazzilu almala-ikata illa bialhaqqi wama kanoo ithan munthareena

Word by Word:

Not We send down the Angels except with the truth; and not they would be then given respite.

Translations:

[Yet] We never send down angels otherwise than in accordance with the [demands of] truth; and [were the angels to appear now,] lo! they [who reject this divine writ] would have no further respite!

We send not the angels down except for just cause: if they came (to the ungodly), behold! no respite would they have!

We send not down the angels save with the Fact, and in that case (the disbelievers) would not be tolerated.

We send not angels but with truth, and then they would not be respited.

We do not send down the angels except with truth; and the disbelievers would not then be reprieved.
