Sahih al-Bukhari 2239
حَدَّثَنَا عَمْرُو بْنُ زُرَارَةَ، أَخْبَرَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، أَخْبَرَنَا ابْنُ أَبِي نَجِيحٍ، عَنْ عَبْدِ اللَّهِ بْنِ كَثِيرٍ، عَنْ أَبِي الْمِنْهَالِ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ قَدِمَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْمَدِينَةَ، وَالنَّاسُ يُسْلِفُونَ فِي الثَّمَرِ الْعَامَ وَالْعَامَيْنِ ـ أَوْ قَالَ عَامَيْنِ أَوْ ثَلاَثَةً. شَكَّ إِسْمَاعِيلُ ـ فَقَالَ " مَنْ سَلَّفَ فِي تَمْرٍ فَلْيُسْلِفْ فِي كَيْلٍ مَعْلُومٍ، وَوَزْنٍ مَعْلُومٍ ".
Amr ibn Zurara narrated to us: Ismail ibn Ulayya informed us: Ibn Abi Najih informed us, from Abdullah ibn Kathir, from Abu al-Minh al, from Ibn Abbas, may Allah be pleased with them both, who said: The Messenger of Allah came to Medina while people were making advance payments for produce for one or two years—or he said two or three years. Ismail was uncertain. He said: “Whoever makes an advance payment for dates should do so for a known measure and a known weight.”
