«وَأَسْتَقِلُّ الْجَزِيلَ لِلنَّزِيلِ»
I consider even a large gift too little for a guest.
Al-jazīl signifies something abundant or generous; al-nazīl is a guest who has stopped at one's lodging. Astaqillu means “I reckon it little.” The speaker is not reporting that the gift is objectively small; he is declaring exceptional standards of hospitality.
The matching sound of al-jazīl / al-nazīl enhances the line, while the meaning centres on honouring a guest beyond a merely adequate payment.
