Surah Ghafir 40:33

يَوْمَ تُوَلُّونَ مُدْبِرِينَ مَا لَكُم مِّنَ ٱللَّهِ مِنْ عَاصِمٍ ۗ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِنْ هَادٍ

The Day you will turn your backs fleeing; there is not for you from Allāh any protector. And whoever Allāh sends astray - there is not for him any guide.

Translation: Saheeh International

Tafsir

a day when you will turn back to flee from the site of the Reckoning leading to the Fire not having anyone to defend you to protect you from God in other words from His chastisement and whomever God leads astray for him there is no guide.
