He is only a plain warner. 184 Have they, then, never considered [God's] mighty dominion over the heavens and the earth, and all the things that God has created, and [asked themselves] whether, perchance, the end of their own term might already have drawn nigh? In what other tiding, then, will they, after this, 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 you about the Resurrection, as to when it is destined; say, “Indeed its knowledge is with my Lord; only He will manifest it at its time; it is proving cumbersome in the heavens and the earth; it will not come to you except suddenly”; they question you as if you have researched it deeply; say, “Indeed its knowledge is with Allah only but most people do not know.” 187 Say: 'I have no power to profit for myself; or hurt, but as God will. Had I knowledge of the Unseen I would have acquired much good, and evil would not have touched me. I am only a warner, and a bearer of good tidings, to a people believing.' 188
