بَابُ جَامِعِ بَيْعِ الطَّعَامِComprehensive Chapter on Sale of Food
Hadith 1357B4
قَالَ مَالِكٌ : وَذَلِكَ أَنَّ أَهْلَ الْعِلْمِ أَنْزَلُوهُ عَلَى وَجْهِ الْمَعْرُوفِ، وَلَمْ يُنْزِلُوهُ عَلَى وَجْهِ الْبَيْعِ، وَذَلِكَ مِثْلُ الرَّجُلِ يُسَلِّفُ الدَّرَاهِمَ النُّقَّصَ، فَيُقْضَى دَرَاهِمَ وَازِنَةً فِيهَا فَضْلٌ، فَيَحِلُّ لَهُ ذَلِكَ، وَيَجُوزُ وَلَوِ اشْتَرَى مِنْهُ دَرَاهِمَ نُقَّصًا بِوَازِنَةٍ، لَمْ يَحِلَّ ذَلِكَ، وَلَوِ اشْتَرَطَ عَلَيْهِ حِينَ أَسْلَفَهُ وَازِنَةً، وَإِنَّمَا أَعْطَاهُ نُقَّصًا لَمْ يَحِلَّ لَهُ ذَلِكَ. ¤
Imam Malik, may Allah have mercy on him, said that this is because the people of knowledge have considered custom and practice in these matters, and have not regarded them like a sale. An example of this is that if a person gives deficient, underweight coins, and then the recipient gives him full-weight coins in return, this is permissible. However, the sale of deficient coins in exchange for full-weight coins is not permissible. If, at the time of making the salam contract, the person stipulated to give deficient, underweight coins and receive full-weight coins, then it will not be valid.
