Appears 2 times in the Quran. (Root: ضيق)
  1. Therefore (for) whomsoever Allah intends that He would guide him aright, He expands his breast for Islam, and (for) whomsoever He intends that He should cause him to err, He makes his breast strait and narrow as though he were ascending upwards; thus does Allah lay uncleanness on those who do not believe.

  2. And when they are cast into a narrow place in it, bound, they shall there call out for destruction.
