حَدَّثَنَا سُفْيَانُ عَنِ ابْنِ أَبِي نَجِيحٍ عَنْ عَبْدِ اللَّهِ بْنِ كَثِيرٍ عَنْ أَبِي الْمِنْهَالِ عَنِ ابْنِ عَبَّاسٍ قَدِمَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْمَدِينَةَ وَهُمْ يُسَلِّفُونَ فِي التَّمْرِ السَّنَتَيْنِ وَالثَّلَاثَ فَقَالَ مَنْ سَلَّفَ فَلْيُسَلِّفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ إِلَى أَجَلٍ مَعْلُومٍ
مسند امام احمد بن حنبل · Hadith 1937
It was narrated that Ibn 'Abbas said: When the Messenger of Allah (PBUH) came to Madinah, the people used to pay two or three years in advance for dates. He said: "Whoever pays in advance, let him pay in advance for a specified measure and a specified weight, for a specified time."
