نَزَلَ الْقُرْآنُ أَرْبَعَةَ أَرْبَاعٍ رُبُعٌ فِينَا وَ رُبُعٌ فِي عَدُوِّنَا وَ رُبُعٌ سُنَنٌ وَ أَمْثَالٌ وَ رُبُعٌ فَرَائِضُ وَ أَحْكَامٌ.
“The Holy Quran came in four parts: One fourth is about us (Ahl al-Bayt) one fourth about our enemies, one about traditions and axioms and one fourth about obligations and laws.”
