كَيْفَ الْمَزَارُ وَقَدْ تَرَبَّعَ أَهْلُهَا بِعُنَيْزَتَيْنِ وَأَهْلُنَا بِالْغَيْلَمِ
How could a meeting take place when her people are spending the spring at ʿUnayzatayn and ours are at al-Ghaylam?
Kayfa al-mazār is a question that makes the impossibility or difficulty of visiting tangible. Tarabbaʿa here means to stay somewhere during the spring, not to divide into four.
ʿUnayzatayn/al-Ghaylam refer to distinct encampments. The expression wa-ahlunā sets the poet’s people against the beloved’s people in parallel clauses.
