وَنَزَعْنَا مِن كُلِّ أُمَّةٍ شَهِيدًا فَقُلْنَا هَاتُوا بُرْهَانَكُمْ فَعَلِمُوا أَنَّ الْحَقَّ لِلَّهِ وَضَلَّ عَنْهُم مَّا كَانُوا يَفْتَرُونَ (75)
(28:75) And We shall bring forth from every nation a witness *92 and say, "Bring now your proof. ' *93 Then they will come to know that the Truth is with AIlah alone, and all falsehoods that they had forged will vanish.
*92) A witness": the Prophet who had warned that community, or a rightly-guided person from among the followers of the Prophets, who had performed the duty of preaching the Truth in the community, or a means through which the message of the Truth had reached the community .
*93) That is, "Present a cogent argument in your defence so that you are pardoned. You should either prove that the shirk and the denial of the Hereafter and Prophethood in which you persisted were the correct creed and you had adopted it on rational grounds, or, if you cannot do that, you should at least prove that no arrangement had been made by God to warn you of this error and guide you to the right path."
