Hadith 1381B3

قَالَ مَالِك : وَإِنَّمَا كُرِهَ ذَلِكَ، لِأَنَّهُ إِنَّمَا يُعْطِيهِ ثَمَنَ مَا بَاعَهُ بِعَيْنِهِ وَيُؤَخِّرُ عَنْهُ الْمِائَةَ الْأُولَى إِلَى الْأَجَلِ الَّذِي ذَكَرَ لَهُ آخِرَ مَرَّةٍ، وَيَزْدَادُ عَلَيْهِ خَمْسِينَ دِينَارًا فِي تَأْخِيرِهِ عَنْهُ، فَهَذَا مَكْرُوهٌ وَلَا يَصْلُحُ، وَهُوَ أَيْضًا يُشْبِهُ حَدِيثَ زَيْدِ بْنِ أَسْلَمَ فِي بَيْعِ أَهْلِ الْجَاهِلِيَّةِ، إِنَّهُمْ كَانُوا إِذَا حَلَّتْ دُيُونُهُمْ، قَالُوا لِلَّذِي عَلَيْهِ الدَّيْنُ : إِمَّا أَنْ تَقْضِيَ وَإِمَّا أَنْ تُرْبِيَ، فَإِنْ قَضَى أَخَذُوا، وَإِلَّا زَادُوهُمْ فِي حُقُوقِهِمْ وَزَادُوهُمْ فِي الْأَجَلِ
Imam Malik, may Allah have mercy on him, said: This is because the creditor has received the price of his item, one hundred dinars, and the term of the one hundred dinars that were a loan has been extended, in exchange for fifty dinars, from which he gains benefit in selling that item. This sale is similar to what Zayd bin Aslam narrated, that in the time of ignorance, when the term of a loan would expire, the creditor would say to the debtor: either pay the loan or give interest. If he paid, he would take it; if not, he would extend the term and increase the loan.
