وَ رَوَى اَلرَّيَّانُ بْنُ اَلصَّلْتِ قَالَ: كَتَبْتُ إِلَى أَبِي مُحَمَّدٍ عَلَيْهِ اَلسَّلاَمُ مَا اَلَّذِي يَجِبُ عَلَيَّ يَا مَوْلاَيَ فِي غَلَّةِ رَحًى فِي أَرْضِ قَطِيعَةٍ لِي وَفِي ثَمَنِ سَمَكٍ وَبَرْدِيٍّ وَقَصَبٍ أَبِيعُهُ مِنْ أَجَمَةِ هَذِهِ اَلْقَطِيعَةِ فَكَتَبَ» يَجِبُ عَلَيْكَ فِيهِ اَلْخُمُسُ إِنْ شَاءَ اَللَّهُ تَعَالَى«.
And al-Rayyan ibn al-Salt narrated, saying:
I (narrator) wrote to Abu Muhammad عليه السلام, peace be upon him: “What is obligatory upon me, my master, regarding the yield of a mill on land granted to me, and regarding the price of fish, papyrus (bardi), and reeds that I sell from the thicket of this granted land?” Imam عليه السلام wrote: "Khums is obligatory upon you in it, if Allah سبحانه وتعالى the Exalted wills."
