﴿ إِنَّ ٱلَّذِينَ كَفَرُوا۟ لَن تُغْنِىَ عَنْهُمْ أَمْوَٰلُهُمْ وَلَآ أَوْلَٰدُهُم مِّنَ ٱللَّهِ شَيْـًۭٔا ۖ وَأُو۟لَٰٓئِكَ أَصْحَٰبُ ٱلنَّارِ ۚ هُمْ فِيهَا خَٰلِدُونَ ﴾

“[But,] behold, as for those who are bent on denying the truth - neither their worldly possessions nor their children will in the least avail them against God: and it is they who are destined for the fire, therein to abide.”

(Lo! the riches) the abundance of riches (and the progeny) and the abundance of progeny (of those who disbelieve) in Muhammad and in the Qur'an, i.e. Ka'b [Ibn al-Ashraf] and his followers (will not avail them aught against Allah) will not avail them against the punishment of Allah; (and such are rightful owners of the Fire) the dwellers of hell. (They will abide therein) for ever.
