And those who deny Our revelations - step by step We lead them on from whence they know not. 182 for, behold, though I may give them rein for a while. My subtle scheme is exceedingly firm! 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Have they not pondered deeply regarding the kingdom of the heavens and the earth, and whatever things Allah created? And that possibly their promise (of death) may have come near? So after this*, in what will they believe? (*Advent of the Last Prophet and the Holy Qur’an.) 185 Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy. 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: I do not control any benefit or harm for my own soul except as Allah please; and had I known the unseen I would have had much of good and no evil would have touched me; I am nothing but a warner and the giver of good news to a people who believe. 188
