Surah Al-An'am (The Cattle), Verse 51

وَاَنْذِرْ بِهِ الَّذِیْنَ یَخَافُوْنَ اَنْ یُّحْشَرُوْۤا اِلٰی رَبِّهِمْ لَیْسَ لَهُمْ مِّنْ دُوْنِهٖ وَلِیٌّ وَّلَا شَفِیْعٌ لَّعَلَّهُمْ یَتَّقُوْنَ ۟

Wa anzir bihil lazeena yakhaafoona ai yuhsharooo ilaa Rabbihim laisa lahum min doonihee waliyyunw wa laa shafee'ul la'allahum yattaqoon

“Give the warning to those in whose (hearts) is the fear that they will be brought (to judgment) before their Lord: except from Him they will have no protector nor intercessor: that they may guard (against evil).”

Quran 6:51 (Yusuf Ali Translation)
