3860 - وَ رَوَى اَلْعَلاَءُ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ قَالَ : سَأَلْتُهُ عَنِ اَلرَّجُلِ يَدْفَعُ اَلطَّعَامَ إِلَى اَلطَّحَّانِ فَيُقَاطِعُهُ عَلَى أَنْ يُعْطِيَ صَاحِبَهُ لِكُلِّ عَشَرَةِ أَمْنَانٍ عَشَرَةَ أَمْنَانِ دَقِيقٍ قَالَ "لاَ" فَقُلْتُ فَرَجُلٌ يَدْفَعُ اَلسِّمْسِمَ إِلَى اَلْعَصَّارِ فَيَضْمَنُ لَهُ بِكُلِّ صَاعٍ أَرْطَالاً مُسَمَّاةً فَقَالَ "لاَ".
Hadith.3860 - Al-Ala' narrated from Muhammad bin Muslim, from one of the imams (peace be upon them), who said: I asked Imam (as) about a man who gives grain to a miller and agrees with him to receive ten measures of flour for every ten measures of grain. Imam (as) said: "No." I then asked: "What about a man who gives sesame seeds to an oil presser and guarantees to receive a specified amount of oil for each measure?" Imam (as) said: "No."
