«وَأَغْمُرُ الزَّمِيلَ بِالْجَمِيلِ»
I shower a fellow traveller with kindness.
Al-zamīl is a companion on the road; al-jamīl is beautiful conduct, goodness or favour. Aghmuru conveys covering or overwhelming, suggesting benefits so plentiful that they surround the companion.
The line depicts abundant practical generosity rather than a vague benevolent feeling. The similar ending of zamīl and jamīl contributes to its memorable cadence.
