كَأَنَّ ذُرَى رَأْسِ الْمُجَيْمِرِ غُدْوَةً / مِنَ السَّيْلِ وَالْغُثَّاءِ فَلْكَةُ مِغْزَلِ
In the morning, the summit of al-Mujaymir amid floodwater and floating debris seemed like the round whorl of a spindle.
Dhurā are high peaks, ghuthāʾ is the floating litter and debris carried by water, and falkat mighzal is a spindle whorl, a small rounded piece used in spinning.
