لَّن تُغْنِىَ عَنْهُمْ أَمْوَٰلُهُمْ وَلَآ أَوْلَـٰدُهُم مِّنَ ٱللَّهِ شَيْـًٔا ۚ أُو۟لَـٰٓئِكَ أَصْحَـٰبُ ٱلنَّارِ ۖ هُمْ فِيهَا خَـٰلِدُونَ
Lan tughniya 'anhum amwaaluhum wa laaa awladuhum minal laahi shai'aa; ulaaa 'ika As haabun Naari hum feehaa khaalidoon
neither their wealth nor their children will be of any use to them against God- they will be the inhabitants of Hell, where they will remain.
Neither their wealth nor their children will avail them anything against God. They are the companions of the fire, and there they will remain.
The verb here is tughniya, built on ghinā, which means wealth and sufficiency both, so the Arabic says that riches will not make them rich. Wealth and children are the standard pair in the Qur'an for everything a person accumulates and hands on, the two things that outlast a single life. This verse follows one about oaths sworn as cover, and it closes off the other cover a person might reach for.
