The following are my notes from the chapter on al-Ribaa (interest) from the Hanbali text Akhsar al-Mukhtasarat. The source of the notes are my teacher Sh. Muhammad Gamal Aly with whom I am studying the text and Sh. Bajabir’s commentary on the book.
- Definition
- Ribaa means an increase in a particular item. The word is derived from a root meaning increase or growth
- It is prohibited according to the Qur’an, Sunnah, and consensus of the scholars
- It is one of the seven major destructive sins
- It does not refer to any and every type of growth in a sale but only particular types of growth
- Typically occurs in items sold in measurements or weights
- This means any exchange transaction that is not done based on measurement/weight cannot be usurious
- Ex: gold, silver, salt, dates, barley, wheat, copper, meat, iron, etc.
- Because all such items are either typically sold in measurement (dates, barley, wheat) or weight (gold, silver, iron, copper, meat)
- Typically occurs in items sold in measurements or weights
- Ribaa means an increase in a particular item. The word is derived from a root meaning increase or growth
- There are two types of interest (ribaa) that are prohibited in Islam: Surplus and deferred payment
- Surplus (fadhl) – ربا الفضل
- Def: When you exchange the same type of goods based on measurement/weight but with a surplus and the exchange is done immediately
- Even if the measurement/weight is small and insignificant in size, it is not allowed
- Same type examples: gold for gold, silver for silver, dates for dates, etc.
- Ex: you sell 10 grams of gold for 15 grams of gold to be exchanged immediately, you sell a saa’ of dates for a mudd of dates to be exchanged immediately, etc.
- Saa’ is a full two handfuls of something and mudd is four full two handfuls of something
- Ex: you sell 10 grams of gold for 15 grams of gold to be exchanged immediately, you sell a saa’ of dates for a mudd of dates to be exchanged immediately, etc.
- Conditions for it to be considered the prohibited ribaa al-fadhl:
- Both exchanges are of same type
- So if the exchange is for different types, for example, selling gold for silver, then it would be permissible if there is a surplus because they are of different types
- One receives a surplus in return
- So if the exchange is in equal amount of measurement/weight for the same type, then it would be permissible
- Exchange happens immediately
- Meaning the buyer and seller both take possession of their commodities immediately
- If the exchange does not take place immediately, then it would be the second type of ribaa discussed below
- Both exchanges are of same type
- Based on the above, the exchange is valid and you can avoid ribaa al-fadhl if:
- The commodities are equal in measurement/weight when of same type
- Ex: 20 grams of gold for 20 grams of gold, a saa’ of dates for a saa’ of dates, etc.
- If they are of different types, then they are not required to be equal
- Ex: 20 grams of gold for 30 grams of silver, a saa’ of dates for a mudd of barley, etc.
- The exchange must happen before they separate regardless of whether the commodities being exchanged are of the same type or not
- Meaning the buyer and seller both take possession of their commodities immediately
- Exception: it is permissible to delay the payment if someone wishes to purchase a weighed/measured commodity (other than gold/silver) with gold/silver/cash
- Ex: someone purchases iron in weight and wishes to pay for it in gold/silver/cash after a month
- Cash is considered a type of gold/silver
- The commodities are equal in measurement/weight when of same type
- It is neither permitted nor valid to exchange commodities of same type calculated originally in measurements through weights and vice versa
- Weights and measurements are considered separate types of calculations
- Ex 1: selling a saa’ of dates for a kilo of dates
- Saa’ is a measurement and kilo is a weight. Dates are originally calculated in measurements and not weights
- Because there is a possibility that they may not be equal in measurement
- Ex 2: selling 2 grams of silver for 2 saa’ of silver
- Grams is a weight and saa’ is a measurement. Silver is originally calculated in weights and not measurements
- Because there is a possibility that they may not be equal in weight
- Exception: if it is known that they both are equal in their original standard calculation
- Ex: if someone sells a saa’ of dates for a kilo of dates and the latter was measured to assure that it was also a saa’ because dates are originally calculated through measurement
- Def: When you exchange the same type of goods based on measurement/weight but with a surplus and the exchange is done immediately
- Deferred payment (nasee’ah) – ربا النسيئة
- Relates to delay in timing
- Meaning the possession of goods is delayed and is not done immediately
- Def: When you exchange goods based on weights/measures but it is delayed
- Ex: you sell 10 grams of gold for 10 grams of gold to be paid after a month
- Notice that even if there is no surplus between the same types, it would still be considered ribaa al-nasee’ah
- Even if the goods are of different types but calculated under the same category, it would still be considered ribaa al-nasee’ah
- Ex: you sell 10 grams of gold for 15 grams of silver to be paid after a month
- Gold and silver both belong under the same category of weights
- Ex: you sell 10 grams of gold for 15 grams of silver to be paid after a month
- Exception: it is valid to delay the payment if someone wishes to purchase a weighed/measured commodity (other than gold/silver/cash) with gold/silver/cash
- Ex: someone purchases meat in weight and wishes to pay for it in gold/silver/cash after a month
- Ex: you sell 10 grams of gold for 10 grams of gold to be paid after a month
- The following are valid:
- To exchange a commodity sold in measurement for a commodity sold in weight and vice versa
- Ex: to sell 5 mudd of dates for 3 grams of gold
- Mudd is a measurement and gold is a weight
- In this case, it is allowed to be exchanged either immediately or through a delay
- It also is not required to be equal
- The same goes for exchanging something measured/weighed for anything else that is not sold in measurements/weights
- Ex: selling a saa’ of dates for a t-shirt
- Ex: to sell 5 mudd of dates for 3 grams of gold
- To exchange gold for silver and vice versa is valid but:
- If the two parties separate before complete possession takes place, then whatever was not exchanged becomes invalid
- Ex: a seller exchanges 10 grams of gold for 20 grams of silver. The seller receives the 20 grams of silver but only pays 5 grams of gold and says that he will give the rest next month
- This will invalidate the 5 grams that he owes because the exchange must happen immediately
- Ex: a seller exchanges 10 grams of gold for 20 grams of silver. The seller receives the 20 grams of silver but only pays 5 grams of gold and says that he will give the rest next month
- If the two parties separate before complete possession takes place, then whatever was not exchanged becomes invalid
- To exchange a commodity sold in measurement for a commodity sold in weight and vice versa
- Relates to delay in timing
- Surplus (fadhl) – ربا الفضل
- To sum up the rules:
- We first look to see if the two exchanges are of usurious types
- Meaning we find out if it is something sold based on measurement/weight
- If both are of the same category, then it is required that they be exchanged immediately
- Ex: weights for weights (gold for silver) or measurements for measurements (dates for barley)
- Exception: to purchase a weighed/measured commodity (other than gold/silver/cash) with gold/silver/cash
- In such a case, it is allowed to be delayed
- If both are of the same category and type, then it is required that they be exchanged immediately and be equal in amount
- Ex: gold for gold, dates for dates, etc.
- If both are from different categories, then it is not required that they be exchanged immediately nor that they be equal in amount
- Ex: weights for measurements (copper for dates), non-usurious types of exchanges (t-shirts for shoes), weights/measurements for non-usurious types (copper/dates for clothes)
- We first look to see if the two exchanges are of usurious types
