Dr. Monzer Kahf, a prominent economist and counselor states: It is permissible to trade stocks provided with two conditions: 1) one must trade only permissible stocks. There are certain criteria about permissibility that include the permissibility of main line of business and that the company is not loaded with no permissible transactions/contracts, and 2) that the trading (of stock) contract is permissible. For instance the AAOIFI (Auditing and Accounting Organization of Islamic Financial Institutions) resolved that buying stock on future delivery or on a loan from broker are not permissible.”
