Hadith 6613778 - وَ رَوَى حَمَّادٌ عَنِ اَلْحَلَبِيِّ قَالَ : سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يَشْتَرِي طَعَاماً فَيَكُونُ أَحْسَنَ لَهُ وَ أَنْفَقَ أَنْ يَبُلَّهُ مِنْ غَيْرِ أَنْ يَلْتَمِسَ زِيَادَةً فَقَالَ "إِنْ كَانَ لاَ يُصْلِحُهُ إِلاَّ ذَلِكَ وَ لاَ يُنْفِقُهُ غَيْرُهُ مِنْ غَيْرِ أَنْ يَلْتَمِسَ فِيهِ اَلزِّيَادَةَ فَلاَ بَأْسَ وَ إِنْ كَانَ إِنَّمَا يَغُشُّ بِهِ اَلْمُسْلِمِينَ فَلاَ يَصْلُحُ".
Hadith.3778 - Hammad narrated from Al-Halabi, who said:
I asked Abu Abdillah (as) about a man who buys food and finds it more suitable and marketable if he moistens it, without intending to increase its weight.
Imam (as) said: "If it cannot be preserved or sold without doing that, and there is no intention of increasing its weight, then there is no harm.
But if the purpose is to deceive the Muslims, then it is not permissible."
