1313. hadíth
وَ رَوَى إِسْحَاقُ بْنُ عَمَّارٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: "لاَ تَسْتَأْجِرِ اَلْأَرْضَ بِالتَّمْرِ وَ لاَ بِالْحِنْطَةِ وَ لاَ بِالشَّعِيرِ وَ لاَ بِالْأَرْبِعَاءِ وَ لاَ بِالنِّطَافِ" قُلْتُ وَ مَا اَلْأَرْبِعَاءُ قَالَ "اَلشِّرْبُ وَ اَلنِّطَافُ فَضْلُ اَلْمَاءِ وَ لَكِنْ تَتَقَبَّلُهَا بِالذَّهَبِ وَ اَلْفِضَّةِ وَ اَلنِّصْفِ وَ اَلثُّلُثِ وَ اَلرُّبُعِ ".
Ishaq bin Ammar narrated from Abu Abdillah (a.s) who said: "Do not rent land in exchange for dates, wheat, barley, water shares (arbi'a'), or surplus water (nitaaf)." I asked: "What is arbi'a'?" Imam (a.s) said: "It means water shares, and nitaaf refers to surplus water. However, you may lease the land for gold, silver, half, a third, or a quarter."
