مِن قَبۡلُ هُدًى لِّلنَّاسِ وَأَنزَلَ ٱلۡفُرۡقَانَ ۗ إِنَّ ٱلَّذِينَ كَفَرُواْ بِـَٔايَٰتِ ٱللَّهِ لَهُمۡ عَذَابٌ شَدِيدٌ ۗ وَٱللَّهُ عَزِيزٌ ذُو ٱنتِقَامٍ

before, that is to say, before revealing it [Al-Qur'an], as guidance (hudan, a circumstantial qualifier meaning, haadiyeen, 'guides from error') to people, to those who followed these two [Books] (He uses the word anzala for the revelation of these two, and nazzala for that of Al-Qur'an, for the latter entails repetition, whereas the two Books were revealed in one instance); and He revealed the Criterion (al-furqaan), meaning the Scriptures that discriminate between truth and falsehood. He mentions this [Criterion] after He has mentioned the three Scriptures so that it encompasses all [revealed Scriptures] besides these. As for those who disbelieve in God's signs, Al-Qur'an or any other [revelation], for them awaits a terrible chastisement; God is Mighty, victorious in His affair, so that nothing can prevent Him from effecting His promise and His threat; Lord of Retribution, with a severe punishment for those that disobeyed Him, the like of which none can do.
