Ask them, "Whose testimony is the most reliable?" Say "Allah is witness11 between me and you (that I am His Messenger), and this Qur'an has been revealed to me so that I should thereby warn you and all whom it may reach. What, will you really testify that there are other deities besides Allah?"12 Say, "As for me, I will never testify such a thing."13 Say, "Indeed, He alone is the Deity and I feel disgusted with the shirk you practice." Those, to whom We have given the Book, recognize this with as much certainty as they recognize their own sons.14 But those, who have made themselves liable to perdition, do not believe in this. And, who can be more unjust than the one who brings false allegations against Allah15 or denies Allah's Signs?16 Indeed, such unjust people can never attain to true success. On the Day, when We muster them all together, We shall ask the mushrikin, "Where are now your associates whom you had taken for your deities?" Then they shall not be able to play any other trick (than make this false statement): "We swear by You, our Lord, we were not at all mushrikin." Behold, how they will invent a lie against themselves and how all the false gods, they had forged, will forsake them! There are some among them, who (pretend to) listen to what you say, but they do not understand it, as We have cast veils over their hearts; We have made them hard of hearing (so they are deaf17 to what they hear). Even if they see any Sign, they will not believe in it; so much so that when they come and contend with you, those, who have already made up their minds not to believe (after hearing all), say, "This is nothing but the same old story."18 They forbid other people to believe in this Truth, and themselves turn away from it. (They imagine that in this way they are doing you some harm), whereas they are preparing their own perdition, though they do riot perceive it. Would that you could see their condition at the time, when they will be made to stand before Hell! They will say, "Would that we could somehow return to the earthly life again: then we would not deny the Signs of our Lord, and would join the Believers." As a matter of fact, they will say this because the Reality which they had concealed before this, will have appeared manifest before them.19 But the fact is that even if they were sent back to the earthly life, they would do all that they had been forbidden to do. They are liars (that is why they will give vent to such a false wish). Today they say, "There is no other life than this our worldly life, and we shall never be raised back to life after our death." Would that you could witness the scene, when they will be brought before their Lord: then their Lord will ask them, "Is this not the Reality?" They will say, "Yes, our Lord, this is the Reality." Then He will declare, "Well, taste the torment for denying this Reality."
