Verse 18

وَأَنذِرْهُمْ يَوْمَ ٱلْـَٔازِفَةِ إِذِ ٱلْقُلُوبُ لَدَى ٱلْحَنَاجِرِ كَـٰظِمِينَ مَا لِلظَّـٰلِمِينَ مِنْ حَمِيمٍ وَلَا شَفِيعٍ يُطَاعُ

And warn them of the approaching day when the terrified hearts will reach their throats, full of remorse. The transgressors will have no friends and no intercessor will be obeyed.
