Surah Yunus Verse 19 - English Translation by Abul Ala Maududi
Surah Yunusوَمَا كَانَ ٱلنَّاسُ إِلَّآ أُمَّةٗ وَٰحِدَةٗ فَٱخۡتَلَفُواْۚ وَلَوۡلَا كَلِمَةٞ سَبَقَتۡ مِن رَّبِّكَ لَقُضِيَ بَيۡنَهُمۡ فِيمَا فِيهِ يَخۡتَلِفُونَ
Once all men were but a single community; then they disagreed (and formulated different beliefs and rites). Had it not been that your Lord had already so ordained, a decisive judgement would have been made regarding their disagreements
