Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 and I respite them, My stratagem is firm. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Do they not consider the kingdom of the heavens and the earth and whatever things Allah has created, and that may be their doom shall have drawn nigh; what announcement would they then believe in after this? 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 you concerning the Hour, when will its coming be? Say: 'The knowledge of it is with my Lord alone: none but He will disclose it at its time. That will weigh heavily on the heavens and the earth; and it shall not come to you other than all of a sudden.' They ask you - as if you are eagerly inquisitive about it - concerning it. Say to them: 'The knowledge of it is with none except Allah. But most people are unaware of this reality.' 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
