«وَرَقَّ ثَوْبُ الْأَصِيلِ وَانْقَطَعَ لِأَجْلِهِ صَوْبُ التَّحْصِيلِ»
The fabric of late afternoon grew thin, and the course of collecting funds ceased with the fading light.
Al-aṣīl denotes late afternoon. Its waning light is imagined as thinning cloth. The nearby sounds of thawb / ṣawb and aṣīl / taḥṣīl make the prose musical. The prose converts the ordinary fact that collections stop at dusk into an elegant image of time wearing away.
«خُذْ مَا رَاجَ وَدَعْ عَنْكَ اللَّجَاجَ وَعَلَيَّ فِي غَدٍ أَنْ أَتَوَصَّلَ إِلَى أَنْ يَنْضَّ لَكَ الْبَاقِي وَيَتَحَصَّلَ»
Take what is now available and abandon obstinacy; tomorrow I shall see that the remaining money becomes payable and collected.
The governor wants the matter resolved but does not have the entire sum ready. Rāja / lajāj creates an emphatic rhyme. Yanḍḍ points to money becoming available in cash, not an amount already paid. This postponement gives the elder an excuse to hold on to the youth.
