Those who reject Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), We shall gradually seize them with punishment in ways they perceive not. 182 And I will give them respite; indeed My secret plan is extremely solid. 183 Have they not pondered that their companion [i.e. the Prophet Muhammad] is not afflicted with insanity? He is only a plain warner. 184 Do they not look into the realm of the heavens and the earth and everything that Allah has created and [think] that perhaps their appointed time has come near? So in what statement hereafter will they believe? 185 Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy. 186 They ask thee concerning the Hour, when will its coming be? Say thou: knowledge thereof is with my Lord only: none shall disclose it at its time but He; heavy it is in the heavens and the earth; it shall not come upon you except on a sudden. They ask thee as though thou wert familiar therewith. Say thou: knowledge thereof is with Allah only; but most of men know not. 187 (Muhammad), say, "I have no control over my benefits or sufferings, without the will of God. Had I known about the unseen, I would have gained much good and would have faced no suffering. I am only a warner and I preach the glad news to the believing people." 188
