Is replacing a spare part in a rented car without the owner's knowledge, while giving the owner the difference in cost, considered an unlawful act? And what should be done if it is?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
What you and the tenant did is an unauthorized disposition of someone else's property, which is an aggression and a betrayal. This is based on the Prophet's (peace be upon him) saying: "All of a Muslim is inviolable to another Muslim: his blood, his wealth, and his honor." Therefore, you must return the car's spare parts to its owner, and it is not permissible for you to possess them.
