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
Indeed, those who dispute concerning the signs of Allah without [any] authority having come to them - there is not within their breasts except pride, [the extent of] which they cannot reach. So seek refuge in Allah. Indeed, it is He who is the Hearing, the Seeing.
