Surah Yunus Verse 19 - English Translation by Muhammad Sarwar
Surah Yunusوَمَا كَانَ ٱلنَّاسُ إِلَّآ أُمَّةٗ وَٰحِدَةٗ فَٱخۡتَلَفُواْۚ وَلَوۡلَا كَلِمَةٞ سَبَقَتۡ مِن رَّبِّكَ لَقُضِيَ بَيۡنَهُمۡ فِيمَا فِيهِ يَخۡتَلِفُونَ
All people (once) followed one belief. Then they began to follow different beliefs. Had not a word of your Lord (His decision to give every one time and free will) been decreed, God would already have settled their differences
