Is e-marketing permissible if products are purchased from the manager's account and a commission is received, then purchased from one's own e-wallet after a certain amount is available, sometimes with an additional amount from a bank account to complete the purchase and receive a commission, with the aim of increasing the product's ranking and visibility and boosting sales, knowing that all products are permissible and harmless?

If you receive a commission when purchasing a product from a platform, this is permissible under three conditions: 1. Your subscription to the platform must be free. If it requires a fee, then it is a forbidden form of usury because it involves a guaranteed loss and a potential gain. 2. The goods you purchase must be permissible (halal). 3. The purchase must be genuine. It is not permissible to sell to yourself or collude to do so in order to earn the commission.

As for the commission, if it is from the platform, it is a promotional gift. If it is from the seller, it is a price reduction.

Purchasing from your manager's account: 1. If the goal is to earn a commission by returning the products you buy for him, this is forbidden. 2. If the intention is to use his account for purchasing from the platform with his knowledge, there is no harm, and the commission belongs to the purchaser.

There is no harm in transferring money from your bank account to an e-wallet for purchases.
