وَقُلْ إِنِّىٓ أَنَا ٱلنَّذِيرُ ٱلْمُبِينُ

And say, "Indeed, I am the clear warner" -

كَمَآ أَنزَلْنَا عَلَى ٱلْمُقْتَسِمِينَ

Just as We had revealed [scriptures] to the separators

ٱلَّذِينَ جَعَلُوا۟ ٱلْقُرْءَانَ عِضِينَ

Who have made the Qur'an into portions.

فَوَرَبِّكَ لَنَسْـَٔلَنَّهُمْ أَجْمَعِينَ

So by your Lord, We will surely question them all

عَمَّا كَانُوا۟ يَعْمَلُونَ

About what they used to do.
