Sura al-Māʾidah 5:48

وَأَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ مِنَ ٱلْكِتَٰبِ وَمُهَيْمِنًا عَلَيْهِ فَٱحْكُم بَيْنَهُم بِمَآ أَنزَلَ ٱللَّـهُ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ عَمَّا جَآءَكَ مِنَ ٱلْحَقِّ لِكُلٍّ جَعَلْنَا مِنكُمْ شِرْعَةً وَمِنْهَاجًا وَلَوْ شَآءَ ٱللَّـهُ لَجَعَلَكُمْ أُمَّةً وَٰحِدَةً وَلَٰكِن لِّيَبْلُوَكُمْ فِى مَآ ءَاتَىٰكُمْ فَٱسْتَبِقُوا۟ ٱلْخَيْرَٰتِ إِلَى ٱللَّـهِ مَرْجِعُكُمْ جَمِيعًا فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ
