And those who cry lies to Our signs We will draw them on little by little whence they know not; 182 And (for this purpose) I will grant them respite. My design is incontrovertible. 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, 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 God lets go astray, there is no guide; and He shall leave them in their overweening arrogance, blindly stumbling to and fro. 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
