3878 - وَ رُوِيَ عَنِ اَلْحَسَنِ بْنِ عَلِيٍّ اَلْوَشَّاءِ قَالَ : سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ اِشْتَرَى مِنْ رَجُلٍ أَرْضاً جُرْبَاناً مَعْلُومَةً بِمِائَةِ كُرٍّ عَلَى أَنْ يُعْطِيَهُ مِنَ اَلْأَرْضِ فَقَالَ "حَرَامٌ " قُلْتُ جُعِلْتُ فِدَاكَ فَإِنِ اِشْتَرَى مِنْهُ اَلْأَرْضَ بِكَيْلٍ مَعْلُومٍ وَ حِنْطَةٍ مِنْ غَيْرِهَا فَقَالَ "لاَ بَأْسَ بِذَلِكَ".
Hadith.3878 - It is narrated from Al-Hasan bin Ali Al-Washsha' who said: I asked Abu Al-Hasan 
about a man who purchased a specified number of plots of land from another man for one hundred kurr, with the condition that he would give him the payment from the yield of the land.
Imam said: "This is forbidden."
I said: "May I be your ransom, what if he purchases the land with a specified measure and with wheat from elsewhere?"
Imam said: "There is no harm in that."
