But as for those who are bent on giving the lie to Our messages - We shall bring them low, step by step, without their perceiving how it came about: 182 And I will give them respite; indeed My secret plan is extremely solid. 183 Why will they not understand that their companion (Muhammad) is not possessed by jinn. (Muhammad) is only a (Divinely) authorized preacher. 184 Do they not consider the kingdom of the heavens and the earth and whatever things Allah has created, and that may be their doom shall have drawn nigh; what announcement would they then believe in after this? 185 Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy. 186 THEY WILL ASK thee [O Prophet] about the Last Hour: "When will it come to pass?" Say: "Verily, knowledge thereof rests with my Sustainer alone. None but He will reveal it in its time. Heavily will it weigh on the heavens and the earth; [and] it will not fall upon you otherwise than of a sudden." They will ask thee - as if thou couldst gain insight into this [mystery] by dint of persistent inquiry! Say: "Knowledge thereof rests with my Sustainer alone; but [of this] most people are unaware." 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
