Is it permissible to participate in a company that sells and rents out scooters to the public, with a specific period set for the buyer to invest the scooters in exchange for profits for both parties?

The answer can be summarized in three points:

First: It is not permissible to invest in this activity except after verifying the existence of the company and the scooters, and that they are actually being rented out. Relying on the internet is not sufficient, as it could be a trick for fraud or for investing money in unlawful activities.

Second: If the transaction is genuine, then the purchased scooter must be known either by sight or by precise description. It is permissible to authorize the company to rent it out for a known fee, or for a percentage of the rental fee according to the Hanbali school of thought.

Third: Upon terminating the transaction, you must receive the scooters as they are your property. It is not permissible to stipulate in the contract a financial compensation upon withdrawal, because that would be an invalid contingent sale.
