Quran 5:48 from Surah Al-Maaida on Divine Marvels.
وَأَنزَلۡنَآ إِلَيۡكَ ٱلۡكِتَٰبَ بِٱلۡحَقِّ مُصَدِّقٗا لِّمَا بَيۡنَ يَدَيۡهِ مِنَ ٱلۡكِتَٰبِ وَمُهَيۡمِنًا عَلَيۡهِۖ فَٱحۡكُم بَيۡنَهُم بِمَآ أَنزَلَ ٱللَّهُۖ وَلَا تَتَّبِعۡ أَهۡوَآءَهُمۡ عَمَّا جَآءَكَ مِنَ ٱلۡحَقِّۚ لِكُلّٖ جَعَلۡنَا مِنكُمۡ شِرۡعَةٗ وَمِنۡهَاجٗاۚ وَلَوۡ شَآءَ ٱللَّهُ لَجَعَلَكُمۡ أُمَّةٗ وَٰحِدَةٗ وَلَٰكِن لِّيَبۡلُوَكُمۡ فِي مَآ ءَاتَىٰكُمۡۖ فَٱسۡتَبِقُواْ ٱلۡخَيۡرَٰتِۚ إِلَى ٱللَّهِ مَرۡجِعُكُمۡ جَمِيعٗا فَيُنَبِّئُكُم بِمَا كُنتُمۡ فِيهِ تَخۡتَلِفُونَ
English translation: And We revealed to you the Book in [the] truth confirming what (was) before his hands of the Book and a guardian over it So judge between them by what has revealed Allah and (do) not follow their vain desires when has come to you of the truth For each We have made for you a law and a clear way And if (had) willed Allah He (would have) made you a community one [and] but to test you in what He (has) given you so race (to) the good To Allah you will return all then He will inform you of what you were concerning it differing
