Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 And I will give them time. Indeed, my plan is firm. 183 Have they not bethought themselves their companion is not mad? He is only a plain admonisher. 184 Have they not looked into the realms of the heavens and the earth and all that God created, and seen that the end of their time might be near? What will they believe in if they do not believe in this? 185 None can guide those whom Allah leaves in error. He leaves them in their insolence, wandering blindly. 186 They ask you about the Hour: "When is its determined time?" Say: "Only my Lord has the knowledge. No one can reveal it except He. Oppressive will it be for the heavens and the earth. When it comes, it will come unawares." They ask you about it as if you were in the know. You tell them: "Only God has the knowledge." But most people do not know. 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
