Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 For though I give them rein for a while, My strategy is sure. 183 Have they not bethought them (that) there is no madness in their comrade? He is but 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 Whomsoever Allah sendeth astray, no guide is then for him, and He letteth them wander perplexed in their exorbitance. 186 They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know. 187 Say: I do not control any benefit or harm for my own soul except as Allah please; and had I known the unseen I would have had much of good and no evil would have touched me; I am nothing but a warner and the giver of good news to a people who believe. 188
