يَتَجَرَّعُهُۥ وَلَا يَكَادُ يُسِيغُهُۥ وَيَأْتِيهِ ٱلْمَوْتُ مِن كُلِّ مَكَانٍۢ وَمَا هُوَ بِمَيِّتٍۢ ۖ وَمِن وَرَآئِهِۦ عَذَابٌ غَلِيظٌۭ
Which he sippeth but can hardly swallow, and death cometh unto him from every side while yet he cannot die, and before him is a harsh doom.
Surah Ibrahim(14:17)
