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 Though I have given them a respite, My plan against them is well established. 183 Have they not reflected? No madness is in their comrade; he is naught but a plain warner. 184 Do they see nothing in the government of the heavens and the earth and all that Allah hath created? (Do they not see) that it may well be that their terms is nigh drawing to an end? In what message after this will they then believe? 185 Whoever Allah sends astray - there is no guide for him. And He leaves them in their transgression, wandering blindly. 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: "I have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith." 188
