موطا امام مالك رواية يحييٰ
Muwatta Imam Malik (Riwayat Yahya)
كتاب البيوعBook: On the Rulings of Buying and Selling
بَابُ بَيْعِ الطَّعَامِ بِالطَّعَامِ لَا فَضْلَ بَيْنَهُمَاChapter on Sale of Food for Food Without Excess
Hadith 1355B9
قَالَ مَالِكٌ : وَلَا خَيْرَ فِي الْخُبْزِ قُرْصٍ بِقُرْصَيْنِ، وَلَا عَظِيمٍ بِصَغِيرٍ، إِذَا كَانَ بَعْضُ ذَلِكَ أَكْبَرَ مِنْ بَعْضٍ، فَأَمَّا إِذَا كَانَ يُتَحَرَّى أَنْ يَكُونَ مِثْلًا بِمِثْلٍ فَلَا بَأْسَ بِهِ وَإِنْ لَمْ يُوزَنْ. ¤
Imam Malik, may Allah have mercy on him, said: If flour is sold for wheat in equal measure, there is no objection. But if half a mudd is wheat and half a mudd is flour, and it is sold in exchange for one mudd of wheat, it is not correct, because he has equated the excellence of his wheat by mixing flour with it.
