Ali 'Imran 3:7

هُوَ ٱلَّذِيٓ أَنزَلَ عَلَيۡكَ ٱلۡكِتَٰبَ مِنۡهُ ءَايَٰتٞ مُّحۡكَمَٰتٌ هُنَّ أُمُّ ٱلۡكِتَٰبِ وَأُخَرُ مُتَشَٰبِهَٰتٞۖ فَأَمَّا ٱلَّذِينَ فِي قُلُوبِهِمۡ زَيۡغٞ فَيَتَّبِعُونَ مَا تَشَٰبَهَ مِنۡهُ ٱبۡتِغَآءَ ٱلۡفِتۡنَةِ وَٱبۡتِغَآءَ تَأۡوِيلِهِۦۖ وَمَا يَعۡلَمُ تَأۡوِيلَهُۥٓ إِلَّا ٱللَّهُۗ وَٱلرَّـٰسِخُونَ فِي ٱلۡعِلۡمِ يَقُولُونَ ءَامَنَّا بِهِۦ كُلّٞ مِّنۡ عِندِ رَبِّنَاۗ وَمَا يَذَّكَّرُ إِلَّآ أُوْلُواْ ٱلۡأَلۡبَٰبِ 7

It is He who has sent down to you, [O Muhammad], the Book; in it are verses [that are] precise - they are the foundation of the Book - and others unspecific. As for those in whose hearts is deviation [from truth], they will follow that of it which is unspecific, seeking discord and seeking an interpretation [suitable to them]. And no one knows its [true] interpretation except Allah. But those firm in knowledge say, "We believe in it. All [of it] is from our Lord." And no one will be reminded except those of understanding
