Surah 33. Al-Ahzab, Ayah 16

Lit., "for then" or "in that case" (idhan), signifying here "however it may be".

 Until the end of your short life on earth.

The coward in a fight does not usually save himself from death. He is subject, after desertion, to the fury both of the enemy and of his own side for cowardice and desertion. Assuming that he did escape with his life, where could he go to? The brand of cowardice will be on him, and he will be Subject to the vegeance of his own people. In any case, his life would be in ignominy and would be brief, and he would have lost irretrievably the meed of valour.
