Surah 54. Al-Qamar, Ayah 6

Lit., "something not known (nukur)" - that is, "something that human beings cannot know [i.e., visualize] because they have never met with anything like it" (Zamakhshari).

 Angel Isrâfîl will blow the Trumpet, causing all to be raised from the dead for judgment.

 i.e., the Judgment.

For a time godlessness seems to triumph, but the triumph is short-lived, And in any case there is the great Reckoning of the Day of Judgment.

The angel whose voice will call at the Resurrection and direct all souls. Cf. xx. 108-111.
