A group of people bought a commodity at the expense of one of them. Is it permissible to sell their shares in this commodity?
Anyone who participates in buying a commodity and has a defined share in it is permitted to sell his share in this commodity as long as they acquired it. This is a selling of what one possesses with a defined price. It is not one of the types of selling cash for cash.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
