اقرأ وتدبر الآية 1383 من سورة سُورَةُ يُونُسَ: وَمَا كَانَ النَّاسُ إِلَّا أُمَّةً وَاحِدَةً فَاخْتَلَفُوا ۚ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِنْ رَبِّكَ لَقُضِيَ بَيْنَهُمْ فِيمَا فِيهِ يَخْتَلِفُونَ
وَمَا كَانَ النَّاسُ إِلَّا أُمَّةً وَاحِدَةً فَاخْتَلَفُوا ۚ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِنْ رَبِّكَ لَقُضِيَ بَيْنَهُمْ فِيمَا فِيهِ يَخْتَلِفُونَ
AND [know that] all mankind were once but one single community, and only later did they begin to hold divergent views. And had it not been for a decree- that had already gone forth from thy Sustainer, all their differences would indeed have been settled [from the outset].
