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 respite them -- assuredly My guile is sure. 183 Do they not reflect? There is no madness in their companion (Muhammad SAW). He is but a plain warner. 184 Will they not ponder upon the kingdom of the heavens and the earth, and all that Allah created, and that it may be that their term is drawing near? So, in which speech will they believe thereafter? 185 Whomsoever Allah sendeth astray, no guide is then for him, and He letteth them wander perplexed in their exorbitance. 186 They ask thee of the (destined) Hour, when will it come to port. Say: Knowledge thereof is with my Lord only. He alone will manifest it at its proper time. It is heavy in the heavens and the earth. It cometh not to you save unawares. They question thee as if thou couldst be well informed thereof. Say: Knowledge thereof is with Allah only, but most of mankind know not. 187 Say [O Prophet]: "It is not within my power to bring benefit to, or avert harm from, myself, except as God may please. And if I knew that which is beyond the reach of human perception, abundant good fortune - would surely have fallen to my lot, and no evil would ever have touched me. I am nothing but a warner, and a herald of glad tidings unto people who will believe." 188
