Al-Baqara 2:213

Mankind was just one nation. Then Allah sent prophets with glad tidings and warnings[107], and sent down to them the Scriptures in truth, to judge between people in matters over which they disputed. But none disputed thereafter except out of arrogance after they had received the clear proofs[108]. Then Allah, by His grace, guided those who believed to the truth in which they disputed. For Allah guides whom He wills to a straight path.

[107] Ibn ‘Abbās (رضي الله عنهما) reported: “The time between Adam and Noah was ten centuries. People were on the right path, but then they started disputing over matters of faith. So, Allah sent prophets bearing glad tiding and warning”. ­[Al-Mustadrak of Al-Hākim].
[108] The plight of humans, especially those who lack sincerity and humbleness, is such that the more knowledge they possess, the more haughty and disputatious they become.

Mankind was [of] one religion [before their deviation]; then Allāh sent the prophets as bringers of good tidings and warners and sent down with them the Scripture in truth to judge between the people concerning that in which they differed. And none differed over it [i.e., the Scripture] except those who were given it - after the clear proofs came to them - out of jealous animosity among themselves. And Allāh guided those who believed to the truth concerning that over which they had differed, by His permission. And Allāh guides whom He wills to a straight path.

213. Mankind were one community and Allâh sent Prophets with glad tidings and warnings, and with them He sent down the Scripture in truth to judge between people in matters wherein they differed. And only those to whom (the Scripture) was given differed concerning it after clear proofs had come unto them through hatred, one to another. Then Allâh by His Leave guided those who believed to the truth of that wherein they differed. And Allâh guides whom He wills to the Straight Path.

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.
