وَمَا آتَيْنَاهُم مِّن كُتُبٍ يَدْرُسُونَهَا ۖ وَمَا أَرْسَلْنَا إِلَيْهِمْ قَبْلَكَ مِن نَّذِيرٍ (44)
(34:44) whereas We gave them no Books that they could study nor sent to them any warner before you. *64
*64) That is, "Neither a book from God has come to them before this nor a messenger, who might have taught them to worship and serve others than God. Therefore, they arc denying the invitation to Tauhid being given by the Qur'an and Muhammad (upon whom be Allah's peace) due to sheer ignorance, and not on the basis of any knowledge. They have in fact no authority for this."
