But those who deny Our signs - We will progressively lead them [to destruction] from where they do not know. 182 And (for this purpose) I will grant them respite. My design is incontrovertible. 183 Has it, then, never occurred to them that there is no madness whatever in [this] their fellowman? He is only a plain warner. 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 No one can guide those whom God has caused to go astray and has left to continue blindly in their rebellion. 186 They ask thee about the (final) Hour - when will be its appointed time? Say: "The knowledge thereof is with my Lord (alone): None but He can reveal as to when it will occur. Heavy were its burden through the heavens and the earth. Only, all of a sudden will it come to you." They ask thee as if thou Wert eager in search thereof: Say: "The knowledge thereof is with Allah (alone), but most men know not." 187 Say [O Prophet]: "It is not within my power to bring benefit to, or avert harm from, myself, except as God may please. And if I knew that which is beyond the reach of human perception, abundant good fortune - would surely have fallen to my lot, and no evil would ever have touched me. I am nothing but a warner, and a herald of glad tidings unto people who will believe." 188
