Al-Baqarah - 2:213

كَانَ النَّاسُ أُمَّةً وَاحِدَةً فَبَعَثَ اللّهُ النَّبِيِّينَ مُبَشِّرِينَ وَمُنذِرِينَ وَأَنزَلَ مَعَهُمُ الْكِتَابَ بِالْحَقِّ لِيَحْكُمَ بَيْنَ النَّاسِ فِيمَا اخْتَلَفُواْ فِيهِ وَمَا اخْتَلَفَ فِيهِ إِلاَّ الَّذِينَ أُوتُوهُ مِن بَعْدِ مَا جَاءتْهُمُ الْبَيِّنَاتُ بَغْيًا بَيْنَهُمْ فَهَدَى اللّهُ الَّذِينَ آمَنُواْ لِمَا اخْتَلَفُواْ فِيهِ مِنَ الْحَقِّ بِإِذْنِهِ وَاللّهُ يَهْدِي مَن يَشَاء إِلَى صِرَاطٍ مُّسْتَقِيمٍ
[2:213]
(All) people are a single nation; so Allah raised prophets as bearers of good news and as warners, and He revealed with them the Book with truth, that it might judge between people in that in which they differed; and none but the very people who were given it differed about it after clear arguments had come to them, revolting among themselves; so Allah has guided by His will those who believe to the truth about which they differed and Allah guides whom He pleases to the right path.
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.
Mankind were one community, and Allah sent (unto them) prophets as bearers of good tidings and as warners, and revealed therewith the Scripture with the truth that it might judge between mankind concerning that wherein they differed. And only those unto whom (the Scripture) was given differed concerning it, after clear proofs had come unto them, through hatred one of another. And Allah by His Will guided those who believe unto the truth of that concerning which they differed. Allah guideth whom He will unto a straight path.
