Every divine book at the time of its revelation is revealed with this very objective as explained above and mentioned in other places as well:
كَانَ النَّاسُ أُمَّةً وَاحِدَةً فَبَعَثَ اللَّهُ النَّبِيِّينَ مُبَشِّرِينَ وَمُنذِرِينَ وَأَنزَلَ مَعَهُمْ الْكِتَابَ بِالْحَقِّ لِيَحْكُمَ بَيْنَ النَّاسِ فِيمَا اخْتَلَفُوا فِيهِ وَمَا اخْتَلَفَ فِيهِ إِلَّا الَّذِينَ أُوتُوهُ مِنْ بَعْدِ مَا جَاءَتْهُمْ الْبَيِّنَاتُ بَغْيًا بَيْنَهُمْ فَهَدَى اللَّهُ الَّذِينَ آمَنُوا لِمَا اخْتَلَفُوا فِيهِ مِنْ الْحَقِّ بِإِذْنِهِ وَاللَّهُ يَهْدِي مَنْ يَشَاءُ إِلَى صِرَاطٍ مُسْتَقِيمٍ
[They present differences among people as a pretext for their hypocrisy. They should know that initially] mankind was once one community. [Then differences surfaced between them]. So God sent forth prophets as bearers of glad tidings and as warners, and with these He sent down His Book as the decisive truth so that it may settle these differences between men. And the fact is that only those differed to whom it was given, after very clear signs had come to them because of malice for one another. So God guided by the backing of His grace those who believed [in the Quran] in all these differences regarding the truth, and God guides whom He intends [according to His law] to the straight path. (2:213)
