TABARANI 11264:
from Ibn ʿAbbās —
[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."
الطبراني ١١٢٦٤:
عن ابن عباس —
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»
