As for those who reject Our signs as false, We shall lead them, step by step, to their ruin without their even perceiving it. 182 I will just give them respite. My plan is certainly invincible. 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 Have they, then, never considered [God's] mighty dominion over the heavens and the earth, and all the things that God has created, and [asked themselves] whether, perchance, the end of their own term might already have drawn nigh? In what other tiding, then, will they, after this, 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 have no autonomy to benefit or hurt myself, except what Allah wills; and were I to procure knowledge of the hidden on my own, it would be that I had accumulated a lot of good; and no misfortune would touch me; I am purely a Herald of Warning and Glad Tidings to the people who believe.” 188
