2- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ لا تَسْتَأْجِرِ الأرْضَ بِالتَّمْرِ وَلا بِالْحِنْطَةِ وَلا بِالشَّعِيرِ وَلا بِالأرْبِعَاءِ وَلا بِالنِّطَافِ قُلْتُ وَمَا الأرْبِعَاءُ قَالَ الشِّرْبُ وَالنِّطَافُ فَضْلُ الْمَاءِ وَلَكِنْ تَقَبَّلْهَا بِالذَّهَبِ وَالْفِضَّةِ وَالنِّصْفِ وَالثُّلُثِ وَالرُّبُعِ.
2. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from Ishaq ibn ‘Ammar from abu Basir who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘You must not rent land in exchange for dates, wheat, barley, al-Arbi‘a’ or al-Nitaf.’ I then asked, ‘What is al-Arbi‘a?’ He (the Imam) said, ‘It is a small amount of water and al-Nitaf means extra water, but rent it in exchange for gold or silver, for half of the produce, one-third or one-fourth.’”
