Hadith 6253742 - وَ قَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ : "مَاكِسِ اَلْمُشْتَرِيَ فَإِنَّهُ أَطْيَبُ لِلنَّفْسِ وَ إِنْ أَعْطَى اَلْجَزِيلَ فَإِنَّ اَلْمَغْبُونَ فِي بَيْعِهِ وَ شِرَائِهِ غَيْرُ مَحْمُودٍ وَ لاَ مَأْجُورٍ".
Hadith.3742 - Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (as) said:
"Bargain with the buyer, for it is more satisfying to the soul. Even if he gives generously, the one who is cheated in buying or selling is neither praiseworthy nor rewarded."
