Quran 10:19 Yunus, ayah 19 of 109

وَمَا كَانَ ٱلنَّاسُ إِلَّآ أُمَّةً وَٰحِدَةً فَٱخْتَلَفُوا۟ ۚ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَقُضِىَ بَيْنَهُمْ فِيمَا فِيهِ يَخْتَلِفُونَ ۝١٩

10:19 Mankind were but one community; then they differed; and had it not been for a word that had already gone forth from thy Lord it had been judged between them in respect of that wherein they differ.
