القرآن:١١١:٢ –

مَا أَغْنَىٰ عَنْهُ مَالُهُ وَمَا كَسَبَ  

{ما أَغنى عنه ماله وما كسب} أي وكسبه، أي ولده ما أغنى بمعنى يغني.

quran:15:84 –

So nothing availed them ˹from˺ what they used to earn.  

And so that which they used to count as gain, in the way of building fortresses and amassing riches, did not avail, ˹did not˺ protect, them, from the chastisement.
القرآن:١٥:٨٤ –

فَمَا أَغْنَىٰ عَنْهُمْ مَا كَانُوا يَكْسِبُونَ  

{فما أغنى} دفع {عنهم} العذاب {ما كانوا يكسبون} من بناء الحصون وجمع الأموال.
quran:26:207 –

They would not be availed by the enjoyment with which they were provided.  

in what way (mā here is interrogative) would that enjoyment which they were given avail them?, in averting the chastisement or mitigating it? It would be of no avail!
القرآن:٢٦:٢٠٧ –

مَا أَغْنَىٰ عَنْهُمْ مَا كَانُوا يُمَتَّعُونَ  

{ما} إستفهامية بمعنى: أي شيء {أغنى عنهم ما كانوا يمتعون} في دفع العذاب أو تخفيفه أي: لم يغن.
