وَ رَوَى اَلْعَلاَءُ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ: فِي اَلرَّجُلِ يَشْتَرِي اَلْمَتَاعَ جَمِيعاً بِثَمَنٍ ثُمَّ يُقَوِّمُ كُلَّ ثَوْبٍ بِمَا يَسْوَى حَتَّى يَقَعَ عَلَى رَأْسِ مَالِهِ يَبِيعُهُ مُرَابَحَةً ثَوْباً ثَوْباً قَالَ "لاَ حَتَّى يُبَيِّنَ لَهُ أَنَّهُ إِنَّمَا قَوَّمَهُ ".
Al-'Ala narrated from Muhammad ibn Muslim, from one of the Imams (a.s), regarding a man who purchases goods altogether for a set price and then appraises each garment based on its value until it equals his capital, selling it item by item at a profit Imam (a.s) said: "No, not until he clarifies to the buyer that he merely appraised it."
