Quran 3:7 from Surah Aal-i-Imraan on Divine Marvels.
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 وَٱلرَّٰسِخُونَ فِي ٱلۡعِلۡمِ يَقُولُونَ ءَامَنَّا بِهِۦ كُلّٞ مِّنۡ عِندِ رَبِّنَاۗ وَمَا يَذَّكَّرُ إِلَّآ أُوْلُواْ ٱلۡأَلۡبَٰبِ
