قَالَ مَالِك : مَنِ اشْتَرَى مُصْحَفًا أَوْ سَيْفًا أَوْ خَاتَمًا وَفِي شَيْءٍ مِنْ ذَلِكَ ذَهَبٌ أَوْ فِضَّةٌ بِدَنَانِيرَ أَوْ دَرَاهِمَ، فَإِنَّ مَا اشْتُرِيَ مِنْ ذَلِكَ وَفِيهِ الذَّهَبُ بِدَنَانِيرَ فَإِنَّهُ يُنْظَرُ إِلَى قِيمَتِهِ، فَإِنْ كَانَتْ قِيمَةُ ذَلِكَ الثُّلُثَيْنِ وَقِيمَةُ مَا فِيهِ مِنَ الذَّهَبِ الثُّلُثَ، فَذَلِكَ جَائِزٌ لَا بَأْسَ بِهِ إِذَا كَانَ ذَلِكَ يَدًا بِيَدٍ وَلَا يَكُونُ فِيهِ تَأْخِيرٌ، وَمَا اشْتُرِيَ مِنْ ذَلِكَ بِالْوَرِقِ مِمَّا فِيهِ الْوَرِقُ نُظِرَ إِلَى قِيمَتِهِ، فَإِنْ كَانَ قِيمَةُ ذَلِكَ الثُّلُثَيْنِ وَقِيمَةُ مَا فِيهِ مِنَ الْوَرِقِ الثُّلُثَ، فَذَلِكَ جَائِزٌ لَا بَأْسَ بِهِ إِذَا كَانَ ذَلِكَ يَدًا بِيَدٍ، وَلَمْ يَزَلْ ذَلِكَ مِنْ أَمْرِ النَّاسِ عِنْدَنَا
Imam Malik, may Allah have mercy on him, said that if a person buys the Noble Qur'an, or a sword, or a ring in which there is gold or silver, in exchange for rupees or gold coins, then it should be seen: if there is gold attached to these things and it is bought in exchange for gold coins, and the price of that item is not less than two-thirds, and the value of the gold attached to it is not more than one-third, then it is permissible as long as it is a cash-for-cash transaction. Similarly, if there is silver attached and it is bought in exchange for rupees, then the same ruling applies.
