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 And (for this purpose) I will grant them respite. My design is incontrovertible. 183 Have they not reflected? There is no madness in their companion, he is but a plain warner. 184 Do they not look into the realm of the heavens and the earth and everything that Allah has created and [think] that perhaps their appointed time has come near? So in what statement hereafter will they believe? 185 No one can guide those whom God lets go astray: He leaves them blundering about in their arrogance. 186 They ask you (Muhammad), "When will the Day of Judgment be?" Tell them, "My Lord knows best. It is He who has appointed its time. It will be a grave hour both in the heavens and the earth. It will only approach you suddenly." They say, "It seems that you know about the coming of the Day of Judgment." Tell them, "Only God knows about it and most people do not know." 187 (Muhammad), say, "I have no control over my benefits or sufferings, without the will of God. Had I known about the unseen, I would have gained much good and would have faced no suffering. I am only a warner and I preach the glad news to the believing people." 188
