Allah is entitled to most excellent names:141 so call Him by excellent names only and leave alone those who deviate froth the Truth in giving names to Him; they shall be recompensed for what they have been doing.142 From among those We have created, there are some who guide with the truth and do justice therewith. As regards those who have treated Our Revelations as false, We will gradually lead them on to ruin in a way they will not know. Though I am giving them a respite, My plan is infallible. And have they never reflected on this matter? There is no tinge of unsoundness of mind in their companion; he is a Warner, who is warning plainly (beforehand of the evil consequence). Have they never considered the functioning of the heavens and the earth, and have they never observed closely anything that Allah has created?143 And has it never occurred to them that their life might have come near to its end?144 Then what else can there be in which they will believe after this warning of the Messenger? Whomever Allah deprives of guidance has no guide, for Allah leaves such people wandering about blindly in their contumacy. These people ask you: "Well, when is the Hour of Resurrection coming?" Say, "Its knowledge is with my Lord alone: He Himself will disclose it at the proper time: that Hour will weigh heavily on the heavens and the earth. It will come on you all of a sudden. " They ask you about it as though you have been in search for it. Say; "Its knowledge is with Allah alone, but most of the people do not know this. " Tell them, O Muhammad, "I have not the power to bring any good to or avert any harm from myself: only that happens which Allah wills. Had I the knowledge of the unseen, I would have acquired many benefits for myself and would never have suffered any harm.145 I am merely a Warner, and a bearer of good news to those who believe in what I say."
