Surat Yunus (Jonas) - يونس

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

And people are naught but a single nation, so they disagree; and had not a word already gone forth from your Lord, the matter would have certainly been decided between them in respect of that concerning which they disagree.
