«كَانَ النَّاسُ أُمَّةً وَاحِدَةً فَبَعَثَ اللَّهُ النَّبِيِّينَ مُبَشِّرِينَ وَمُنْذِرِينَ»
“Humanity was one community, then God sent prophets bearing good news and warning.” (al-Baqarah 2:213, excerpt)
«وَمَا اخْتَلَفَ فِيهِ إِلَّا الَّذِينَ أُوتُوهُ»
“Only those to whom it was given disputed concerning it.” (al-Baqarah 2:213, excerpt)
The long verse revisits disagreement, scripture and guidance at distinct points. Such reiteration keeps the developing argument intelligible while distinguishing stages and responsible groups.
Compressing all those parts into a single vague statement loses the fine distinctions. Even the antecedent of “fīhi” must be understood from the linked discussion rather than from an isolated word.
