عَقِبهِ

Appears 3 times in the Quran. (Root: عقب)
  1. And thus We have made you a medium (just) nation that you may be the bearers of witness to the people and (that) the Messenger may be a bearer of witness to you; and We did not make that which you would have to be the qiblah but that We might distinguish him who follows the Messenger from him who turns back upon his heels, and this was surely hard except for those whom Allah has guided aright; and Allah was not going to make your faith to be fruitless; most surely Allah is Affectionate, Merciful to the people.

  2. 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.

  3. And when the Shaitan made their works fair seeming to them, and said: No one can overcome you this day, and surely I am your protector: but when the two parties came in sight of each other he turned upon his heels, and said: Surely I am clear of you, surely I see what you do not see, surely I fear Allah; and Allah is severe in requiting (evil).
