The Ruling on Investing Shareholders' Funds in an Islamic Company

Question:
The questioner says: Have you heard of the Islamic Investment Company affiliated with the Islamic House of Finance? Have you looked into any of its projects and its method from a Sharia perspective? What is Your Eminence’s opinion of it? If they keep the shareholders' funds in some riba (usury or interest) banks here for a short time until they are sent to their main center, and they are compelled to do so because there is no Islamic bank, do you advise Muslims to invest their funds in this institution, knowing that this supports them?

Answer:
I do not know their system, nor have I looked into their projects. If they use Islamic transactions and conduct Islamic dealings, it does not harm them to deposit some money at a certain time out of necessity, just as you deposit your money and transfer it from one bank to another to avoid need. Just as people deposit their funds in some banks out of need, we do not make it obligatory without interest out of necessity. However, avoiding it and not depositing in them is better if the period is short, and it is not permissible. Rather, in cases of necessity, a deposit without interest does not harm. So, if this Islamic House’s projects and works are Islamic, the mere fact that they may deposit some funds without interest does not harm them either.
