There is no madness in their companion, he is but a plain warner. 184 Do they see nothing in the government of the heavens and the earth and all that Allah hath created? (Do they not see) that it may well be that their terms is nigh drawing to an end?

Say, "Its knowledge is only with my Lord. None will reveal its time except Him. It lays heavily upon the heavens and the earth. It will not come upon you except unexpectedly." They ask you as if you are familiar with it. Say, "Its knowledge is only with Allah, but most of the people do not know." 187 Say, "I myself have no power to benefit or do harm, save as God pleases. If I had knowledge of the unseen, I would have availed myself of an abundance of good, and no harm would have touched me. I am but a warner and a bearer of good tidings for those who will believe." 188
