Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 And I will give them respite; indeed My secret plan is extremely solid. 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 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 will question thee concerning the Hour, when it shall berth. Say: 'The knowledge of it is only with my Lord; none shall reveal it at its proper time, but He. Heavy is it in the heavens and the earth; it will not come on you but suddenly!' They will question thee, as though thou art well-informed of it. Say: 'The knowledge of it is only with God, but most 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
