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.
