On the Day of Resurrection, No Wealth or Offspring Shall Avail

Allah says;

إِنَّ الَّذِينَ كَفَرُواْ لَن تُغْنِيَ عَنْهُمْ أَمْوَالُهُمْ وَلاَ أَوْلاَدُهُم مِّنَ اللّهِ شَيْئًا وَأُولَـئِكَ هُمْ وَقُودُ النَّارِ ﴿١٠﴾

Verily, those who disbelieve, neither their properties nor their offspring will avail them whatsoever against Allah; and it is they who will be fuel of the Fire.

Allah states that the disbelievers shall be fuel for the Fire,

يَوْمَ لاَ يَنفَعُ الظَّـلِمِينَ مَعْذِرَتُهُمْ وَلَهُمُ الْلَّعْنَةُ وَلَهُمْ سُوءُ الدَّارِ

The Day when their excuses will be of no profit to wrongdoers. Theirs will be the curse, and theirs will be the evil abode (i.e. painful torment in Hell-fire). (40:52)

Further, what they were granted in this life of wealth and offspring shall not avail them with Allah, or save them from His punishment and severe torment.

Similarly, Allah said,

فَلاَ تُعْجِبْكَ أَمْوَلُهُمْ وَلاَ أَوْلَـدُهُمْ إِنَّمَا يُرِيدُ اللَّهُ لِيُعَذِّبَهُمْ بِهَا فِي الْحَيَوةِ الدُّنْيَا وَتَزْهَقَ أَنفُسُهُمْ وَهُمْ كَـفِرُونَ

So let not their wealth nor their children amaze you; in reality Allah's plan is to punish them with these things in the life of this world, and that their souls shall depart (die) while they are disbelievers. (9:55)

and,

لاَ يَغُرَّنَّكَ تَقَلُّبُ الَّذِينَ كَفَرُواْ فِى الْبِلَـدِ

مَتَـعٌ قَلِيلٌ ثُمَّ مَأْوَاهُمْ جَهَنَّمُ وَبِئْسَ الْمِهَادُ

Let not the free disposal (and affluence) of the disbelievers throughout the land deceive you. A brief enjoyment; then, their ultimate abode is Hell; and worst indeed is that place for rest. (3:196-197)

Allah said in this Ayah,,

إِنَّ الَّذِينَ كَفَرُواْ ...

Verily, those who disbelieve,

meaning, disbelieved in Allah's Ayat, denied His Messengers, defied His Books and did not benefit from His revelation to His Prophets.

... لَن تُغْنِيَ عَنْهُمْ أَمْوَالُهُمْ وَلاَ أَوْلاَدُهُم مِّنَ اللّهِ شَيْئًا وَأُولَـئِكَ هُمْ وَقُودُ النَّارِ

Neither their properties nor their offspring will avail them whatsoever against Allah; and it is they who will be fuel of the Fire.

meaning, they will be the wood with which the Fire is kindled and fed.

Similarly, Allah said,

إِنَّكُمْ وَمَا تَعْبُدُونَ مِن دُونِ اللَّهِ حَصَبُ جَهَنَّمَ

Certainly you (disbelievers) and that which you are worshipping now besides Allah, are (but) fuel for Hell! (21:98)

Allah said next,
