But as for those who are bent on giving the lie to Our messages - We shall bring them low, step by step, without their perceiving how it came about: 182 For though I give them rein for a while, My strategy is sure. 183 Have they not reflected that their companion is not mad? 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 For those whom Allah lets go astray, there is no guide; and He will leave them in their transgression to stumble blindly. 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 Tell them [O Muhammad]: 'I have no power to benefit or harm myself except as Allah may please. And had I knowledge of the unseen, I should have amassed all kinds of good, and no evil would have ever touched me. I am merely a warner and the herald of glad tidings to those who have faith.' 188
