قَالَ مَالِكٌ : الْأَمْرُ الْمُجْتَمَعُ عَلَيْهِ عِنْدَنَا، أَنْ لَا تُبَاعَ الْحِنْطَةُ بِالْحِنْطَةِ، وَلَا التَّمْرُ بِالتَّمْرِ، وَلَا الْحِنْطَةُ بِالتَّمْرِ، وَلَا التَّمْرُ بِالزَّبِيبِ، وَلَا الْحِنْطَةُ بِالزَّبِيبِ، وَلَا شَيْءٌ مِنَ الطَّعَامِ كُلِّهِ إِلَّا يَدًا بِيَدٍ، فَإِنْ دَخَلَ شَيْئًا مِنْ ذَلِكَ الْأَجَلُ لَمْ يَصْلُحْ، وَكَانَ حَرَامًا، وَلَا شَيْءَ مِنَ الْأُدْمِ كُلِّهَا إِلَّا يَدًا بِيَدٍ. ¤
Imam Malik, may Allah have mercy on him, said: In our view, this ruling is agreed upon that wheat should not be sold for wheat, and dates for dates, and wheat for dates, and dates for grapes, except hand to hand, with no delay on either side. If there is a delay, it becomes unlawful. Similarly, for all the things that are eaten with bread, if one is exchanged for another, it should be taken hand to hand.
