﴿ وَمَا قَدَرُوا۟ ٱللَّهَ حَقَّ قَدْرِهِۦٓ إِذْ قَالُوا۟ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ بَشَرٍۢ مِّن شَىْءٍۢ ۗ قُلْ مَنْ أَنزَلَ ٱلْكِتَٰبَ ٱلَّذِى جَآءَ بِهِۦ مُوسَىٰ نُورًۭا وَهُدًۭى لِّلنَّاسِ ۖ تَجْعَلُونَهُۥ قَرَاطِيسَ تُبْدُونَهَا وَتُخْفُونَ كَثِيرًۭا ۖ وَعُلِّمْتُم مَّا لَمْ تَعْلَمُوٓا۟ أَنتُمْ وَلَآ ءَابَآؤُكُمْ ۖ قُلِ ٱللَّهُ ۖ ثُمَّ ذَرْهُمْ فِى خَوْضِهِمْ يَلْعَبُونَ ﴾

“For, no true understanding of God have they when they say, "Never has God revealed anything unto man." Say: "Who has bestowed from on high the divine writ which Moses brought unto men as a light and a guidance, [and] which you treat as [mere] leaves of paper, making a show of them the while you conceal [so] much - although you have been taught [by it] what neither you nor your forefathers had ever known?" Say: "God [has revealed that divine writ]!" - and then leave them to play at their vain talk.”

When the call of the Prophet Muhammad reached the people of Makkah, some of them asked certain Jews what they thought about it and whether God’s Word had really been revealed to the Prophet Mohammad. The Jews replied that God had not made revelations to any human being. This is obviously very strange, because the Jews themselves accepted a series of prophets, thus tacitly admitting that God’s word had indeed been revealed from time to time to human beings. But when a man blindly opposes anything, he will go to the extent of contradicting his own accepted ideas in the heat of attempting to defeat his opponent.
