And (as to) those who reject Our communications, We draw them near (to destruction) by degrees from whence they know not. 182 and I respite them, My stratagem is firm. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear 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 No one can guide those whom God lets go astray: He leaves them blundering about in their arrogance. 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 myself have no power to benefit or do harm, save as God pleases. If I had knowledge of the unseen, I would have availed myself of an abundance of good, and no harm would have touched me. I am but a warner and a bearer of good tidings for those who will believe." 188
