ٱلْأَنْبِيَاء : ٣٤

  • وَمَا And not
  • جَعَلۡنَا We made
  • لِبَشَرٖ for any man
  • مِّن before you
  • قَبۡلِكَ before you
  • ٱلۡخُلۡدَۖ [the] immortality
  • أَفَإِيْن so if
  • مِّتَّ you die
  • فَهُمُ then (would) they
  • ٱلۡخَٰلِدُونَ live forever
And We did not grant to any man before you eternity [on earth]; so if you die - would they be eternal?
When the disbelievers said that Muhammad may peace and salutation be upon him would die, the following was revealed: And We did not assign to any human being before you immortality, permanence [of life] in this world. What, if you [are fated to] die, will they be immortal?, in it? No! (The last sentence constitutes the [syntactical] locus of the interrogative of denial).
