Like murky oil, it boils within bellies  

Like molten copper, that is to say, like the dregs of black oil (ka’l-muhli, is the second predicate) it will boil inside the bellies (˹if˺ read taghlī, then it is a third predicate; ˹if˺ yaghlī, then it is a circumstantial qualifier referring to al-muhl, ‘molten copper’),

كَالْمُهْلِ يَغْلِي فِي الْبُطُونِ  

{كالمهل} أي كدردي الزيت الأسود خبر ثان {تغلي في البطون} بالفوقانية خبر ثالث وبالتحتانية حال من المهل.
