O people! You have guideposts, so follow your guideposts. And you have an end, so turn toward that end. Indeed, a believer is living between two worries; worry about a passed period of life for which he doesn’t know how Allah will treat him, and what is left of his life wherein he doesn’t know what Allah has decreed for him. So the ‘Abd (servant of Allah) must control himself for his own sake, and must derive benefit from his world for his Hereafter, and from his youth for his old age, and from his life for his death. By Whose hand Muhammad’s soul is! There will be no second chance after death, and there is no other abode after the worldly abode except Paradise or Hell.
