Quran

إِذۡ يَقُولُ ٱلۡمُنَٰفِقُونَ وَٱلَّذِينَ فِي قُلُوبِهِم مَّرَضٌ غَرَّ هَـٰٓؤُلَآءِ دِينُهُمۡۗ وَمَن يَتَوَكَّلۡ عَلَى ٱللَّهِ فَإِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٞ

[Remember] when the hypocrites and those in whose hearts was disease said, "Their religion has deluded those [Muslims]." But whoever relies upon Allah - then indeed, Allah is Exalted in Might and Wise
