A craftsman

A: It is not permissible for the person who fixes fridges to take profits for purchasing spare parts except if the owner of the fridge gives it to him. It is unlawful to take the money (Part No. 15; Page No. 130) of a Muslim person except with his consent. Thus, it is not permissible for him to add extra money that is more than the real value of the spare part. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
