Quran 40:18 from Surah Ghafir on Divine Marvels.
وَأَنذِرۡهُمۡ يَوۡمَ ٱلۡأٓزِفَةِ إِذِ ٱلۡقُلُوبُ لَدَى ٱلۡحَنَاجِرِ كَٰظِمِينَۚ مَا لِلظَّٰلِمِينَ مِنۡ حَمِيمٖ وَلَا شَفِيعٖ يُطَاعُ
English translation: And warn them (of the) Day the Approaching when the hearts (are) at the throats choked Not for the wrongdoers any intimate friend and no intercessor (who) is obeyed
Transliteration: wa-andhir'hum yawma al-azifati idhi al-qulubu lada al-hanajiri kazimina ma lilzzalimina min hamimin wala shafi'in yuta'u
