He is only a plain warner. 184 Do they not look in the dominion of the heavens and the earth and all things that Allah has created, and that it may be that the end of their lives is near. In what message after this will they then believe? 185 For one whom Allah sends astray, there is none to guide him; and He leaves them to wander 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, “I have no autonomy to benefit or hurt myself, except what Allah wills; and were I to procure knowledge of the hidden on my own, it would be that I had accumulated a lot of good; and no misfortune would touch me; I am purely a Herald of Warning and Glad Tidings to the people who believe.” 188
