  • مَا Not
  • نُنَزِّلُ We send down
  • ٱلۡمَلَٰٓئِكَةَ the Angels
  • إِلَّا except
  • بِٱلۡحَقِّ with the truth
  • وَمَا and not
  • كَانُوٓاْ they would be
  • إِذٗا then
  • مُّنظَرِينَ given respite
We do not send down the angels except with truth;1 and they [i.e., the disbelievers] would not then be reprieved.
Footnotes
1 - i.e., with a message or, as the conclusion of the verse suggests, to carry out a promised punishment.
God, exalted be He, says: The angels do not descend (tanazzalu: one of the two taa' letters [of tatanazzalu] has been omitted) save with the truth, with the chastisement; and then, that is, upon the descent of the angels with the chastisement, they [the disbelievers] would not be reprieved, [would not] be granted respite.
