The last characteristic of Islamic capital market will be about the product. Islamic financial products are governed by Islamic commercial law, which forbids riba and gharar (legal ambiguity or undue risk) in transactions. Islamic capital has been surging demand for Islamic products as investors have realised that the Islamic Capital Market strictly abides by Islam's religious values, principles and laws. Through constant innovation and the development of several Islamic products, such as Sukuk, Islamic REIT, Islamic Unit Trusts, and Islamic ETFs Islamic products are being well received globally. While riba is commonly interpreted as interest, it also has broader meanings, such as the prohibition of debt sale. Conventional markets such as REIT, Unit Trust, ETF, and modern derivatives such as forwards, futures, swaps, and options are also prohibited since they contain aspects of both riba and gharar. Because interest is prohibited, Islamic finance structures financial goods using a variety of other permissible arrangements. The most common types of contracts utilized in practice are sale, lease, partnership, and agency. Two stages of screening are applied to the universe of all stocks to identify Shariah compatible stocks. The first screening is a qualitative business activity screening that weeds out businesses that are engaging in illegal items and services. Tobacco, alcohol, pornography, weapons, casino games, pork-related items, traditional banking institutions, and so on are the examples as stated on the third features. Companies that pass the qualitative screening are then subjected to a quantitative financial screening. Financial screenings determine the acceptable criteria for excluding enterprises with unsatisfactory levels of traditional debt, liquidity, interest-based investment, and/or impure income (Khatkhatay & Nisar, 2006; Derigs & Marzban, 2008). Shariah compatible equities are those that pass both qualitative and quantitative screening.
For the first product, Sukuk are financial instruments that reflect equity, real estate, usufruct, money, debt, or any combination of these. Sukuk holders are the owners of the rights and bear the risks associated with these instruments. Sukuks can have fixed or variable returns and can be traded, depending on the contractual basis. Sukuk that represent debt or money are not negotiable and can only be traded for their face value. Thus, along with equity shares, instruments can be securitised and traded at negotiable prices if these represent real physical assets or usufruct. The types of instruments examined in capital markets will determine the linkages between the Islamic and conventional divisions.
Furthermore, a group of professional fund managers manages a unit trust fund, which invests the pooled money in a portfolio of securities. This type of diversified portfolio allows investors to spread their assets out, minimizing portfolio risk in the event that some investments lose value while also increasing the chances of finding good stocks at good prices. As a result, mutual funds have become major investment vehicles for small and individual investors. It is also a vital conduit for capital transfer from households to productive sectors. As a result of its strategic implications for investment position, the topic of unit trust performance has gotten a lot of attention from practitioners and academics. As for Shariah-compliant unit trust funds, it is the investment funds that adhere to the criteria of Shariah law and Islamic principles. Islamic unit trust funds are a collective investment scheme that offers investors the opportunity to invest in a diversified portfolio of Shariah-compliant securities, fixed income securities and money market instruments. The investment management of the Islamic funds is not only based on capital market regulation but also on the Shariah principles, whereas the conventional funds are only restricted by the capital market regulation. Investments in non-Shariah compliance enterprises, such as items or services relating to traditional banking, insurance, and financial services, gambling, alcoholic beverages, and non-halal food products, will be excluded from a Shariah compliant unit trust fund. A Shariah-compliant unit trust fund must follow a number of rules, including investing solely in Shariah-compliant enterprises, forming a Shariah Board, conducting an annual Shariah audit, and donating to charity some sources of revenue prohibited by Shariah law, such as interest.
Next, unlike a conventional Exchange Trade Fund that has the liberty to track any benchmark index regardless of the Shariah status of the component stocks, an Islamic ETF tracks only benchmark index where the index constituents are Shariah-compliant companies. Apart from that, the management of i-ETF has to strictly observe the Shariah principles and Islamic investment guidelines. The operation of i-ETF is also overseen by a Shariah board, committee or advisor who would conduct Shariah-compliant audits and reviews from time to time. An Islamic ETF and a conventional ETF share common characteristics. The main difference between a conventional ETF and Islamic ETF is the benchmark index that the Islamic ETF tracks. An Islamic ETF only tracks an Islamic benchmark index where the index constituents comprise companies which are Shariah compliant. An Islamic ETF is also required to appoint a Shariah adviser or committee to provide expertise and guidance to ensure that its structure, investments and all matters related to the funds' activities comply with the Shariah.
Lastly, Islamic real estate investment trusts or I-REITs are collective investment vehicles (typically in the form of trust funds) that pool money from investors and use the pooled capital to buy, manage and sell real estate. I-REITs provide an investment opportunity for those who wish to invest in real estate through Shariah-compliant capital market instruments with some guidelines and principles of Islamic Shariah by investors. Real estate investment trust (REIT) is a collective investment scheme in real estate that combines the best features of real estate and trust fund. i-REIT is the Shariah version of the conventional REIT. In November 2005, The Malaysian Government, through Securities Commission Malaysia (SC) issued Guidelines for Islamic Real Estate Investment Trusts, setting a new global benchmark for the development of this instrument and making Malaysia the first jurisdiction to introduce such guidelines in the industry (Muhammad, 2016). These guidelines provide guidance to market players on Shariah compliance in developing and managing an i-REIT. These guidelines also serve to complement the existing Guidelines on Real Estate Investment Trusts. Al-‘Aqar Healthcare REIT, Axis REIT, KLCC REIT and Al-Salam REIT are those Islamic ETF that are listed in Bursa Malaysia.

CONCLUSION
In conclusion, the capital market, both Islamic and conventional, represents a significant component of the overall financial system, fulfilling such as the facilitation of long-term financing for government and private sector businesses and the provision of much -needed liquidity through a well-functioning secondary market. The differences between the conventional and Islamic capital markets, however, lies in the necessity of the latter's compliances with shariah. The Securities Commission (SC) in Malaysia is responsible for developing screening rules that are used by all publicly traded firms in order to determine their halal status. It is critical to ensure that the business does not contain any forbidden elements. Prohibited activities in Islam, as well as elements such as usury (riba), gambling (maysir), and too much ambiguity, should be avoided in the Islamic capital market (gharar). The Islamic Capital Market contributes significantly to the country's economic prosperity and operates in parallel to the regular capital market, providing individuals and organizations with a variety of investment and financing options. It has grown in numerous ways, including its product and service offerings.
The growth of Islamic capital markets is linked to the development of capital markets in general. The Islamic financial system benefits from capital markets since Islam prohibits interest and encourages trading. The development of Islamic capital markets is a broad subject. It can cover a wide variety of subjects, such as the current condition of the regulatory system and possible improvements, market structure and practices, product range and development, market actors' nature and preferences, and the identification and development of support institutions. Conventional products such as equities, derivatives and bonds convert it to Islamic products such as sukuk, Islamic traded fund (ETF), real estate investment trust (REIT) and many more.
