Surah Al-Baqarah (The Cow), Verse 213

كَانَ النَّاسُ اُمَّةً وَّاحِدَةً فَبَعَثَ اللّٰهُ النَّبِیّٖنَ مُبَشِّرِیْنَ وَمُنْذِرِیْنَ وَاَنْزَلَ مَعَهُمُ الْكِتٰبَ بِالْحَقِّ لِیَحْكُمَ بَیْنَ النَّاسِ فِیْمَا اخْتَلَفُوْا فِیْهِ وَمَا اخْتَلَفَ فِیْهِ اِلَّا الَّذِیْنَ اُوْتُوْهُ مِنْ بَعْدِ مَا جَآءَتْهُمُ الْبَیِّنٰتُ بَغْیًا بَیْنَهُمْ فَهَدَی اللّٰهُ الَّذِیْنَ اٰمَنُوْا لِمَا اخْتَلَفُوْا فِیْهِ مِنَ الْحَقِّ بِاِذْنِهٖ وَاللّٰهُ یَهْدِیْ مَنْ یَّشَآءُ اِلٰی صِرَاطٍ مُّسْتَقِیْمٍ ۟

“Mankind was one single nation, and Allah sent Messengers with glad tidings and warnings; and with them He sent the Book in truth, to judge between people in matters wherein they differed; but the People of the Book, after the clear Signs came to them, did not differ among themselves, except through selfish contumacy. Allah by His Grace Guided the believers to the Truth, concerning that wherein they differed. For Allah guided whom He will to a path that is straight.”
