quran:52:46 –

The Day their plan will not avail them at all, nor will they be helped.  

the day when their guile will avail them nothing (yawma lā yughnī is a substitution for yawmahumu, ‘that day of theirs’) and they will not be helped, they will ˹not˺ be protected from the chastisement in the Hereafter.
القرآن:٥٢:٤٦ –

يَوْمَ لَا يُغْنِي عَنْهُمْ كَيْدُهُمْ شَيْئًا وَلَا هُمْ يُنْصَرُونَ  

{يوم لا يغني} بدل من يومهم {عنهم كيدهم شيئا ولا هم يُنصرون} يمنعون من العذاب في الآخرة.

quran:44:41 –

The Day when no relation will avail a relation at all, nor will they be helped -  

the day when a friend will not avail a friend, on account of kinship or friendship, that is to say, ˹the day when˺ he will not ˹be able to˺ ward off from the other, anything, of the chastisement, nor will they be helped — ˹nor will they˺ be protected from it (yawma, ‘the day’, is a substitution for yawma’l-fasl, ‘the Day of Decision’),
القرآن:٤٤:٤١ –

يَوْمَ لَا يُغْنِي مَوْلًى عَنْ مَوْلًى شَيْئًا وَلَا هُمْ يُنْصَرُونَ  

{يوم لا يغني مولى عن مولى} بقرابة أو صداقة، أي لا يدفع عنه {شيئاً} من العذاب {ولا هم ينصرون} يمنعون منه، ويوم بدل من يوم الفصل.
