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 And I give them rein: verily My contrivance is firm. 183 Do they not reflect? Their companion is not seized with madness: he is but a perspicuous warner. 184 Have they not observed the kingdom of the heavens and the earth, and all that Allah has created and that their term of life might have drawn near After this warning from the Prophet, what will it be that will make them believe? 185 For those whom God lets go astray, there is no guide; and He shall leave them in their overweening arrogance, blindly stumbling to and fro. 186 They ask you about the Hour and when it is to come. Say: 'None knows except my Lord. He alone will reveal it at the appointed time. It is heavy in the heavens and earth. It will not come to you but suddenly' They will question you, as though you had full knowledge of it. Say: 'Its knowledge is with Allah, though most people are unaware' 187 Say thou: I possess no power over benefit or hurt to myself save as Allah willeth; and had I knowledge of the unseen I would have amassed ample good, and evil would not have touched me. I am naught but a warner and a bringer of tidings unto a people who believe. 188
