مَشْمُولَةً غُلِثَتْ بِنَابِتِ عَرْفَجٍ ۞ كَدُخَانِ نَارٍ سَاطِعٍ أَسْنَامُهَا
The smoke-like trail resembles a fire struck by the north wind and fed with ʿarfaj brushwood, sending its thick, towering smoke upward.
Mashmūlah indicates exposure to the north wind. Ghulithat concerns mixing material into the fire, while ʿarfaj is a desert shrub used as brushwood. The preceding verse named smoke; this verse supplies wind and fuel, making the image more concrete.
