And those who cry lies to Our signs We will draw them on little by little whence they know not; 182 for, behold, though I may give them rein for a while. My subtle scheme is exceedingly firm! 183 Has it, then, never occurred to them that there is no madness whatever in [this] their fellowman? He is only a plain warner. 184 Will they not ponder upon the kingdom of the heavens and the earth, and all that Allah created, and that it may be that their term is drawing near? So, in which speech will they believe thereafter? 185 Whoever Allah sends astray - there is no guide for him. And He leaves them in their transgression, wandering blindly. 186 They ask thee of the (destined) Hour, when will it come to port. Say: Knowledge thereof is with my Lord only. He alone will manifest it at its proper time. It is heavy in the heavens and the earth. It cometh not to you save unawares. They question thee as if thou couldst be well informed thereof. Say: Knowledge thereof is with Allah only, but most of mankind know not. 187 Say: 'I do not have the power to acquire benefits or to avert harm from myself, except by the Will of Allah. Had I possessed knowledge of the unseen, I would have availed myself of much that is good, and no harm would have touched me. But I am only a warner and a bearer of glad tidings for a nation who believe. 188
