يَنقَلِبْ

Appears 2 times in the Quran. (Root: قلب)
  1. And Muhammad is no more than a messenger; the messengers have already passed away before him; if then he dies or is killed will you turn back upon your heels? And whoever turns back upon his heels!s, he will by no means do harm to Allah in the least and Allah will reward the grateful.

  2. Then turn back the eye again and again; your look shall '~ come back to you confused while it is fatigued.
