In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Imaam As-Sadi [may Allaah have mercy upon him] said:

What the Sharee’ah brought regarding the permissibility of business transaction, renting, companies (business partnerships), and the types of mutual dealings between the people in which they make exchanges in terms of specific items, debts, beneficial worldly things and other than that: the perfect Sharee’ah came to settle this type of mutual dealing and put it at the disposal of the people, because it includes various affairs of welfare, necessities, needs and luxuries; therefore, the people are given room through which their affairs and circumstances are improved and the sources of their livelihoods are established. The Sharee’ah specified with regards to these affairs that there should be consent of the two parties, including contracts based on knowledge, knowledge of the contracted party, the subject of the contract and knowledge of the conditions that result from it. And it forbids everything that involves harm and injustice, such as the different types of gambling, usury and obscurity regarding an object, sale or price. (see appendix a)

Whoever contemplates the Sharee’ah mutual dealings, he (she) will see their firm connection to sound rectification of the religious and worldly affairs, and will testify to Allaah’s vast Perfect Mercy and Perfect Wisdom, because Allaah permitted all good things for the people, such as (lawful) earnings, foods and drinks, and the well-established ways of attaining beneficial things.

Appendix a: Umar Ibnul Khattaab [may Allaah be pleased wwith him] said: None is to conduct business transaction in our marketplaces, except the one who has acquired understanding in the religion. [Saheeh Sunah Tirmidhee’ Number 487] Shaikh Ahmad Shaakir [may Allaah have mercy upon him] said: Yes, until he knows what to take [from the people] and what to leave; until he knows what is Halaal and what is Haram, so that he neither corrupts the buying nor the selling of the people with falsehood and lies, nor enters them into usury from any angle whilst the buyer is unaware of that. Trade should be based on sound Islamic principles, so that both a Muslim and Non- Muslim are satisfied with it- free from deception and swindle. [Tahqeeq Sunan at-Tirmidhee 2/357]
