وَأَنذِرْ بِهِ ٱلَّذِينَ يَخَافُونَ أَن يُحْشَرُوٓا۟ إِلَىٰ رَبِّهِمْ ۙ لَيْسَ لَهُم مِّن دُونِهِۦ وَلِىٌّۭ وَلَا شَفِيعٌۭ لَّعَلَّهُمْ يَتَّقُونَ
Warn hereby those who fear (because they know) that they will be gathered unto their Lord, for whom there is no protecting ally nor intercessor beside Him, that they may ward off (evil).
