Issue No.1766- The practice of Usury is haram, and it is of two kinds: 1) Usury in loan that will be explained, InshAllah, in the section dealing with loans. 2) Usury in transaction; this means to sell a quantity of a commodity which is sold by weight or volume at a higher rate against the same type of commodity, such as selling three kilos of wheat for 31⁄2 kilos of wheat. In Islamic narrations, usury has been extremely advised against and is considered a major sin.
Issue No.1752- Transactions in the following cases are void:1) To sell and purchase original najis things, i.e., things which are originally najis, like urine, faeces and blood, as an obligatory precaution. Therefore, it is not permissible as an obligatory precaution to sell and purchase najis manure, however there is no harm in using them. Though the sale and purchase of blood which is used to save the life of the injured and the sick in our time, is permissible. Similarly, the sale and purchase of hunting and guard dogs are permitted.2) Sale and purchase of usurped properties. [There would be no problem if the owner permits the transaction]3) Sale and purchase of things which are usually utilised for haram acts, like musical instruments and gambling instruments.4) Sale and purchase of things that among people, are not considered to possess the value of transaction, though they may be of some value to a particular person, like many insects.5) Any transaction which involves usury.6) A transaction which involves fraud or adulteration and the buyer is not informed about it, like selling milk mixed with water, or oil mixed with fat or another thing. This act is called cheating (ghish) or fraud, and it is considered as one of the major sins. It has been narrated that the Holy Prophet of Islam (ṣ) said, “If a person cheats the Muslims in a transaction or harms them, or deceives them, he is not one of us. And when a person cheats his fellow Muslim Allah deprives him of His blessing in that person’s livelihood, closes the means of his earnings and leaves him to himself ”.7) No one can take the possession of isolated lands by registering and it is not permissible to purchase or sell them unless one prepares them for cultivation.
Issue No. 1587- Payment of zakāt becomes obligatory under the following conditions:I. The property should reach the prescribed taxable limit, which will be explained later.II. The owner should be sane and mature.III. The owner should be legally able to benefit from the property. IV. If a person remains the owner of cows, sheep, camels, gold and silver for 12 months, payment of zakāt becomes obligatory for him. However, the obligatory precaution is that payment of zakāt becomes obligatory from the first day of the twelfth month, and if some of the conditions cease to exist during the twelfth month, the zakāt should be paid.
Issue No. 1618- One of the other conditions for zakāt to become obligatory on gold and silver is that they should be in the form of coins and are used for transactions. Therefore, zakāt is not due on coins which are not currency for transaction.
Issue No. 1628- Sheep have five taxable limits:1- 40 sheep, the zakāt of which is one sheep. No zakāt is payable on less than that.2- 121 sheep, the zakāt of which is two sheep.3- 201 sheep, the zakāt of which is three sheep.4- 301 sheep, the zakāt of which is four sheep.5- 400 sheep and more, the zakāt of which is one sheep for each group of 100 sheep, and there is no zakāt on the group of sheep, which is less than 100, and there is also no zakāt for the number of sheep between the two taxable limits. Therefore, if the number of sheep has reached 40, but does not reach the second taxable limit, which is 121, the owner should give only one sheep as zakāt, and the same rule applies to the succeeding taxable limits.
Issue No. 1641- Zakāt should be spent for the following eight purposes:1 & 2 It may be given to poor or destitute persons, and they are the ones who are not able to meet their own expenses, as well as that of their families for a period of one year. The difference between poor or destitute is that the former may not beg anyone for help, but destitute is a needy person who may do so. Those people who have a business, or possess a property or capital or a trade but still are not able to meet their expenses are classified as "Faqir" (poor), and can make up the shortfall of their living through zakāt.3- A person who is a wakīl of the Holy Imam (as) or his representative to collect zakāt, to keep it in safe custody, to maintain its accounts and to deliver it to the Imam or his representative or to spend it in the proper ways, may use zakāt as a wage for the work he has done.4- It may be given to people weak in faith, whose faith is strengthened and they may be inclined to Islam as a result of giving them zakāt. 5- It can be spent to purchase slaves in order to set them free.6- It can be given to indebted persons who are unable to repay their debts.7- It may be spent in the way of Allah, i.e., ways which have public benefit for Muslims. For instance constructing a mosque, a school for religious education, Islamic propagation centres, dispatching propagators, publishing useful Islamic books, and in short, anything which has a benefit for Islam and in whatever way or manner it may be, particularly jihād (holy war) in the way of Allah.8- It may be given to an ibn al-sabīl (a penniless traveller). He can receive zakāt to the extent of his need, although he may be rich and needless in his place of residence.
Issue No. 1654- Second- Giving zakāt should not end up being an aid into sinning. Hence, zakāt should not be given to a person who spends it for sinful purposes, and as an obligatory precaution, it should not be given to a drunkard either.
Issue No. 1526- It is obligatory to pay khums on everything which is extracted from the mines of gold, silver, lead, iron, copper, coal, oil, sulphur, turquoise, salt and any other mines and various metals. The obligatory precaution is that there is no taxable limit (niṣāb). khums therefore, should be paid from whatever quantity extracted from a mine, whether less or more.
Issue No. 1542- If halal property gets mixed with haram property in such a way that it is not possible to identify one from the other, and the owner of the haram property and its quantity are not known, the person concerned should pay khums on the entire property, and the rest will be halal for him.
Issue No. 1548- If one obtains gems like corals, pearls, etc., from the sea-bed by diving into the sea, he should pay khums on them provided that their value, after deducting the expenses of bringing them out, is not less than one mithqāl of coined gold (equal to 3.456 g.), whether they are minerals or things that grow out, or whether the gems were brought out in a single dive or after several successive dives within a time span which is commonly reckoned as one time, and whether they are of the same kind or of different kinds.
Issue No. 1557- If Muslims fight against the unbelievers in compliance with the orders of the Holy infallible Imam (as), khums should be paid on what is acquired from the enemy after deducting the expenses of safe custody, transport, etc., of that property.
Issue No. 1563- If a dhimmī disbeliever (a disbeliever who is living peacefully as a minority alongside Muslims and has accepted the conditions of being a dhimmī), purchases land from a Muslim, the former should pay one-fifth of the land’s produce instead of one-tenth; meaning double the usual zakāt.
