Surah Ash-Shura (The Consultation), Verse 14

وَمَا تَفَرَّقُوْۤا اِلَّا مِنْ بَعْدِ مَا جَآءَهُمُ الْعِلْمُ بَغْیًا بَیْنَهُمْ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِنْ رَّبِّكَ اِلٰۤی اَجَلٍ مُّسَمًّی لَّقُضِیَ بَیْنَهُمْ وَاِنَّ الَّذِیْنَ اُوْرِثُوا الْكِتٰبَ مِنْ بَعْدِهِمْ لَفِیْ شَكٍّ مِّنْهُ مُرِیْبٍ ۟

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

“And they became divided only after Knowledge reached them,- through selfish envy as between themselves. Had it not been for a Word that went forth before from thy Lord, (tending) to a Term appointed, the matter would have been settled between them: But truly those who have inherited the Book after them are in suspicious (disquieting) doubt concerning it.”

Quran 42:14 (Yusuf Ali Translation)
