Qur'an 40:56

إِنَّ ٱلَّذِينَ يُجَـٰدِلُونَ فِىٓ ءَايَـٰتِ ٱللَّهِ بِغَيْرِ سُلْطَـٰنٍ أَتَىٰهُمْ ۙ إِن فِى صُدُورِهِمْ إِلَّا كِبْرٌ مَّا هُم بِبَـٰلِغِيهِ ۚ فَٱسْتَعِذْ بِٱللَّهِ ۖ إِنَّهُۥ هُوَ ٱلسَّمِيعُ ٱلْبَصِيرُ

Lo! those who wrangle concerning the revelations of Allah without a warrant having come unto them, there is naught else in their breasts save pride which they will never attain. So take thou refuge in Allah. Lo! He, only He, is the Hearer, the Seer.
