Surah Yunus, Verse 19

وَمَا كَانَ ٱلنَّاسُ إِلَّآ أُمَّةࣰ وَٰحِدَةࣰ فَٱخۡتَلَفُواْۚ وَلَوۡلَا كَلِمَةࣱ سَبَقَتۡ مِن رَّبِّكَ لَقُضِيَ بَيۡنَهُمۡ فِيمَا فِيهِ يَخۡتَلِفُونَ ﴿١٩﴾

Ve ma kanen nasü illa ümmetev vahıdeten fahtelefu ve lev la kelimetün sebekat mir rabbike le kudiye beynehüm fıma fıhi yahtelifun

“Mankind was but one nation, but differed (later). Had it not been for a word that went forth before from thy Lord, their differences would have been settled between them”
