And those who deny Our revelations - step by step We lead them on from whence they know not. 182 And I respite them; certainly My Plan is strong. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Have they not contemplated the kingdom of the heavens and the earth and everything created by God, (to educe) that perhaps their own term is drawing to a close? In what lore after this would they then believe? 185 Whosoever God allows to go astray has none to show him the way, for He leaves them to wander perplexed in their wickedness. 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 hold not for myself [the power of] benefit or harm, except what Allah has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe." 188
