«أَفَتَأْذَنُ لِي فِي قَصْدِ قَرْيَةٍ لِأَسْتَحِمَّ وَأَقْضِيَ هَذَا الْمُهِمَّ؟»
Will you permit me to visit a village so that I can bathe and attend to this need?
Afataʾdhanu politely requests permission; li-astaḥimma expresses purpose: “so that I may bathe.”
«فَقُلْتُ: إِذَا شِئْتَ فَالسُّرْعَةَ السُّرْعَةَ، وَالرَّجْعَةَ الرَّجْعَةَ»
I answered: If you wish, then go quickly and return quickly.
The doubled nouns al-surʿa / al-rajʿa create insistent emphasis. Permission is granted, but on an implicit expectation of return.
