وَمَا تَفَرَّقُوٓاْ إِلَّا مِنۢ بَعۡدِ مَا جَآءَهُمُ ٱلۡعِلۡمُ بَغۡيَۢا بَيۡنَهُمۡۚ وَلَوۡلَا كَلِمَةٞ سَبَقَتۡ مِن رَّبِّكَ إِلَىٰٓ أَجَلٖ مُّسَمّٗى لَّقُضِيَ بَيۡنَهُمۡۚ وَإِنَّ ٱلَّذِينَ أُورِثُواْ ٱلۡكِتَٰبَ مِنۢ بَعۡدِهِمۡ لَفِي شَكّٖ مِّنۡهُ مُرِيبٖ

Wa maa tafarraqooo illaa mim ba'di maa jaaa'ahumul 'ilmu baghyam bainahum; wa law laa Kalimatun sabaqat mir Rabbika ilaaa ajalim musammal laqudiya bainahum; wa innal lazeena oorisul Kitaaba mim ba'dihim lafee shakkim minhu mureeb
