Surah Yunus Verse 19 - English Translation by Muhammad Mahmoud Ghali
Surah Yunusوَمَا كَانَ ٱلنَّاسُ إِلَّآ أُمَّةٗ وَٰحِدَةٗ فَٱخۡتَلَفُواْۚ وَلَوۡلَا كَلِمَةٞ سَبَقَتۡ مِن رَّبِّكَ لَقُضِيَ بَيۡنَهُمۡ فِيمَا فِيهِ يَخۡتَلِفُونَ
And in no way were mankind anything except one nation, then they differed among themselves; and had it not been for a Word that went before from your Lord, wherein they differed, (it) would indeed have been decreed between them. (i.e., what they differed about would nave been settled)
