Al Ma’idah Ayah 48

وَأَنزَلْنَآ إِلَيْكَ ٱلْكِتَـٰبَ بِٱلْحَقِّ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ مِنَ ٱلْكِتَـٰبِ وَمُهَيْمِنًا عَلَيْهِ‌ۖ فَٱحْكُم بَيْنَهُم بِمَآ أَنزَلَ ٱللَّهُ‌ۖ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ عَمَّا جَآءَكَ مِنَ ٱلْحَقِّ‌ۚ لِكُلٍّ جَعَلْنَا مِنكُمْ شِرْعَةً وَمِنْهَاجًا‌ۚ وَلَوْ شَآءَ ٱللَّهُ لَجَعَلَكُمْ أُمَّةً وَٲحِدَةً وَلَـٰكِن لِّيَبْلُوَكُمْ فِى مَآ ءَاتَـٰكُمْ‌ۖ فَٱسْتَبِقُواْ ٱلْخَيْرَٲتِ‌ۚ إِلَى ٱللَّهِ مَرْجِعُكُمْ جَمِيعًا فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ ٤٨ We have revealed to you ?O Prophet? this Book with the truth, as a confirmation of previous Scriptures and a supreme authority on them. So judge between them by what Allah has revealed, and do not follow their desires over the truth that has come to you. To each of you We have ordained a code of law and a way of life. If Allah had willed, He would have made you one community, but His Will is to test you with what He has given ?each of? you. So compete with one another in doing good. To Allah you will all return, then He will inform you ?of the truth? regarding your differences.
