وَٱتَّقُوا۟ يَوْمًۭا لَّا تَجْزِى نَفْسٌ عَن نَّفْسٍۢ شَيْـًۭٔا وَلَا يُقْبَلُ مِنْهَا عَدْلٌۭ وَلَا تَنفَعُهَا شَفَٰعَةٌۭ وَلَا هُمْ يُنصَرُونَ
And guard (yourselves) against a day when no soul will in aught avail another, nor will compensation be accepted from it, nor will intercession be of use to it; nor will they be helped.
Surah Al-Baqara(2:123)
