 In this segment, we would be further looking into sale contracts or Islamic sale contracts or Sharia compliant sale contracts. Before we look into the sale contracts in further detail in this segment or in some forthcoming segments, it is important to emphasize that trade in Islam is considered as an engine of growth. In Islam, trade is probably the basis of all the businesses. When we look at the literature in Islamic transactions, we find in about 95% cases reference to the sale contracts whenever there is a mention of business. In Urdu, which is called Tijarat, because of the Tijarat itself, many people call it Islam-Halla. Muslims, they have historically been very good when it comes to trading and they excelled in trading in their business as well as they helped the spread of their religion by way of adopting trading. So, in the fiction literature, whenever there is a mention of business, there is a lot of talk of sale contracts and the sale contracts are explained only. And this is probably the reason why Islamic banking and finance has actually adopted a number of Islamic sale contracts for its own business. Hence, we find the application of Muraabah, which is a deferred payment sale contract when we combine it with Bamu Ajil. It is also based on a Salem contract, i.e. Islamic banking is based on Salem contract as well, especially in countries where agriculture and farming are important. Trading and profit are very important to understand both of these. If there is a lot of emphasis on trading in Islam, on Tijarat, then it should be understood that Islam gives permission for profit earning. In the previous segment, I mentioned one sale contract, which is called Tawliya. In case of Tawliya, there is no profit charged by the seller. But this is the hospitality of the seller. Otherwise, no matter how much profit the seller can earn in Islam, as long as he doesn't have a monopoly power, there is no deception, and of course, there is no hoarding, there is no market manipulation, if all these things are not there, then a person who sits in the market for 1 rupee, gives a profit of 1 rupee to 5 rupees, and the competition is there. This is acceptable in an Islamic economic and Islamic financial framework. One more thing, Islam gives permission to sell and buy anything in the market along with a few exceptions. The first thing is that Islam doesn't allow to buy and sell haram goods and services. For example, lottery is haram, gambling is haram in Islam. Hence, if someone says that I am just selling these lotteries, I am not doing anything which is against the teachings of Islam, that person is wrong. If someone is selling alcohol, although that person doesn't drink alcohol, the person cannot say that he is not doing anything wrong. There is also permission to buy and sell haram goods in Islam, and this is something and everyone who is interested in Islamic banking and finance must understand. And this is also a requirement, that the things which are not present, you cannot buy or sell them. The things which are not present, imaginary things, cannot be bought and sold in accordance with Islamic law. The third thing which is important is that the things that are present, but they are not of the seller, they are not of the seller's property, they are not present in the seller's possession, these things cannot be bought and sold. So anything which I don't own, I cannot sell in the market. For example, if my parents own a house, I cannot sell that house because I do not own that house. So, first thing, haram goods and services cannot be bought and sold. Non-existent goods and services cannot be bought and sold, and the goods and the things which someone does not own, they cannot buy and sell these items. Finally, I would also like to say that public goods, historically, Muslims were not allowed to sell them. For example, air cannot be bought and sold, but we see that the air which we fill in our cars is sold. So if someone has come into possession, that is no more a public good. Similarly, historically, this was not allowed to sell water. Today, we buy and drink the water of the people. So this bottled water of the people does not remain public, but if there is public water available, that cannot be bought and sold. In the olden times, the road could not be bought or sold, but nowadays, in modern times, there are tall taxes, so all these things, air, water, right to passage, the use of the road, which was forbidden in the olden times, now governments and in some cases, private organizations, they are involved in the sale and purchase of this kind of goods and services, which is acceptable in Islam as well.
