٨- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ مُحَمَّدِ بْنِ الْحَسَنِ بْنِ شَمُّونٍ عَنِ الأصَمِّ عَنْ مِسْمَعٍ قَالَ قُلْتُ لأبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) إِنَّ لِي أَرْضاً تُطْلَبُ مِنِّي وَيُرَغِّبُونِّي فَقَالَ لِي يَا أَبَا سَيَّارٍ أَمَإ؛ عَلِمْتَ أَنَّ مَنْ بَاعَ الْمَاءَ وَالطِّينَ ذَهَبَ مَالُهُ هَبَاءً قُلْتُ جُعِلْتُ فِدَاكَ إِنِّي أَبِيعُ بِالثَّمَنِ الْكَثِيرِ وَأَشْتَرِي مَا هُوَ أَوْسَعُ رُقْعَةً مِمَّا بِعْتُ قَالَ فَلا بَأْسَ. 
8. A number of our people have narrated from Sahl ibn Ziyad from Muhammad ibn al-Hassan ibn Shammun from al-Asamm from Misma‘ who has said the following: “Once I said to abu ‘Abd Allah , ‘I have a piece of land in which buyers are much interested to purchase.’ He (the Imam) said, ‘O abu Sayyar, do you know that whoever sells land or water (like a fountain for irrigation and so on), his wealth goes away as a bad loss.’ I then said, ‘I pray to Allah to keep my soul in service for your cause, I will sell it for a high price and then I can buy a piece of land bigger than this one.’ He (the Imam) said, ‘Then it is all right.’”
