He who makes an advance payment should not make advance payment except for a specified measure and weight (and for a specified period).
قَدِمَ رَسُولُ اللَّهِ ﷺ وَالنَّاسُ يُسْلِفُونَ فَقَالَ لَهُمْ رَسُولُ اللَّهِ ﷺ مَنْ أَسْلَفَ فَلاَ يُسْلِفْ إِلاَّ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ
Messenger of Allah ﷺ came to Medina and the people used to pay in advance the price of fruits to be delivered within one or two years. (The sub-narrator is in doubt whether it was one to two years or two to three years.) The Prophet ﷺ said, "Whoever pays money in advance for dates (to be delivered later) should pay it for known specified weight and measure (of the dates).
قَدِمَ رَسُولُ اللَّهِ ﷺ الْمَدِينَةَ وَالنَّاسُ يُسْلِفُونَ فِي الثَّمَرِ الْعَامَ وَالْعَامَيْنِ أَوْ قَالَ عَامَيْنِ أَوْ ثَلاَثَةً شَكَّ إِسْمَاعِيلُ فَقَالَ مَنْ سَلَّفَ فِي تَمْرٍ فَلْيُسْلِفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ
Those who pay in advance for anything must do so for a specified weight and for a definite time.
قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَهُمْ يُسْلِفُونَ فِي الثِّمَارِ السَّنَةَ وَالسَّنَتَيْنِ فَقَالَ مَنْ أَسْلَفَ فِي تَمْرٍ فَلْيُسْلِفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ إِلَى أَجَلٍ مَعْلُومٍ
"I heard Ibn 'Abbas say: 'When the Prophet came (to al-Madinah), they used to pay in advance for dates, two or three years in advance. He forbade them that and said: 'whoever pays in advance for dates, let him pay for a known amount or a known weight, to be delivered at a known time'''
قَدِمَ رَسُولُ اللَّهِ ﷺ الْمَدِينَةَ وَهُمْ يُسْلِفُونَ فِي التَّمْرِ السَّنَتَيْنِ وَالثَّلاَثَ فَنَهَاهُمْ وَقَالَ مَنْ أَسْلَفَ سَلَفًا فَلْيُسْلِفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ إِلَى أَجَلٍ مَعْلُومٍ
When the Messenger of Allah ﷺ came to Medina, they were paying one, two and three years in advance for fruits, so he said: Those who pay in advance for anything, must do for a specified measure and weight with a specified time fixed.
قَدِمَ رَسُولُ اللَّهِ ﷺ وَهُمْ يُسْلِفُونَ فِي التَّمْرِ السَّنَةَ وَالسَّنَتَيْنِ وَالثَّلاَثَةَ فَقَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَسْلَفَ فِي تَمْرٍ فَلْيُسْلِفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ إِلَى أَجَلٍ مَعْلُومٍ

[Machine] The Messenger of Allah ﷺ arrived in Medina, and the people were borrowing dates for one or two years or he said, for two years and three years. So he said, "Whoever borrows dates, let him borrow a known measure and a known weight."
قَدِمَ رَسُولُ اللهِ ﷺ الْمَدِينَةَ وَالنَّاسُ يُسَلِّفُونَ فِي التَّمْرِ الْعَامَ وَالْعَامَيْنِ أَوْ قَالَ عَامَيْنِ وَالثَّلاثَةَ فَقَالَ مَنْ سَلَّفَ فِي تَمْرٍ فَلْيُسَلِّفْ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ

"مَنْ أَسْلَفَ في شَيْءٍ، فَليُسْلِفْ في كَيلٍ مَعْلومٍ وَوزْنِ مَعلُومٍ إِلى أَجَلٍ مَعْلُومٍ".
