The Prophet ﷺ came to Medina and the people used to pay in advance the prices of fruits to be delivered within two to three years. The Prophet ﷺ said (to them), "Buy fruits by paying their prices in advance on condition that the fruits are to be delivered to you according to a fixed specified measure within a fixed specified period." Ibn Najih said, " ... by specified measure and specified weight."  

قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَهُمْ يُسْلِفُونَ فِي الثِّمَارِ السَّنَتَيْنِ وَالثَّلاَثَ فَقَالَ أَسْلِفُوا فِي الثِّمَارِ فِي كَيْلٍ مَعْلُومٍ إِلَى أَجَلٍ مَعْلُومٍ وَقَالَ عَبْدُ اللَّهِ بْنُ الْوَلِيدِ حَدَّثَنَا سُفْيَانُ حَدَّثَنَا ابْنُ أَبِي نَجِيحٍ وَقَالَ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ  

[Machine] Al-Qa'ani narrated that Sufyan ibn 'Uyaynah reported from Ibn Abi Najih, on the authority of Abdullah ibn Kathir, on the authority of Abu al-Minhal, on the authority of Ibn Abbas, who said: The Prophet ﷺ arrived in Medina and they were dealing with deferred payment of fruits for two or three years. So he said, "Whoever gives a loan, let him specify a known measure and a known weight and a known term."  

ثنا الْقَعْنَبِيُّ ثنا سُفْيَانُ بْنُ عُيَيْنَةَ عَنِ ابْنِ أَبِي نَجِيحٍ عَنْ عَبْدِ اللهِ بْنِ كَثِيرٍ عَنْ أَبِي الْمِنْهَالِ عَنِ ابْنِ عَبَّاسٍ قَالَ قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَهُمْ يُسْلِفُونَ فِي الثَّمَرِ السَّنَتَيْنِ وَالثَّلَاثَ فَقَالَ «مَنْ أَسْلَفَ فَلْيُسْلِفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ إِلَى أَجْلٍ مَعْلُومٍ»  

[Machine] The Prophet ﷺ arrived in Medina while they were lending in fruit for two or three years. He said, "Whoever lends in fruit, let him lend with a known weight and measure, and for a known period of time." This is the wording of the narration of Amr an-Naqid, and in the narration of Yahya ibn Yahya, it is mentioned as two or three years, and he said, "for a known period of time" without mentioning the word "and". And in the narration of Ash-Shafi'i, it is mentioned as "for a known period of time". Ash-Shafi'i said, "I memorized it as I was described by Sufyan many times, and someone whom I trust informed me that Sufyan said, 'Whenever I mention the word 'to a known period of time', it is referring to a specific period.'"  

قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَهُمْ يُسْلِفُونَ فِي الثَّمَرِ سَنَتَيْنِ وَثَلَاثًا فَقَالَ مَنْ أَسْلَفَ فِي ثَمَرٍ فَلْيُسْلِفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ وَإِلَى أَجَلٍ مَعْلُومٍ هَذَا لَفْظُ حَدِيثِ عَمْرٍو النَّاقِدِ وَفِي رِوَايَةِ يَحْيَى بْنِ يَحْيَى السَّنَتَيْنِ وَالثَّلَاثَ وَقَالَ إِلَى أَجَلٍ مَعْلُومٍ لَمْ يَذْكُرِ الْوَاوَ وَفِي رِوَايَةِ الشَّافِعِيِّ وَأَجَلٍ مَعْلُومٍ قَالَ الشَّافِعِيُّ حَفِظْتُهُ كَمَا وَصَفْتُ مِنْ سُفْيَانَ مِرَارًا وَأَخْبَرَنِي مَنْ أُصَدِّقُهُ عَنْ سُفْيَانَ أَنَّهُ قَالَ كُلَّمَا قُلْتُ وَقَالَ فِي الْأَجَلِ إِلَى أَجَلٍ مَعْلُومٍ
