Is it permissible for a father to use the internet service he brought into the house for free, by dividing the subscription cost among the neighbors alone, and is he sinful for what has passed?

If the father exclusively owns the benefit of internet service, he is permitted to dispose of it, such as by leasing or gifting it. However, if he shares it with others, he must abide by the agreement made with the partners, unless they grant permission otherwise.

To determine whether the father is the sole owner of the benefit or a partner, one should consider who bears the responsibility, maintenance, and cost of the service. If the father bears them alone, he is the owner; otherwise, he is a partner.

Profit is earned through capital, labor, or guarantee. If none of these reasons exist, profit is not deserved.

If it becomes clear that the father was a partner and did not pay his share, it is a debt upon him, and he must seek the partners' forgiveness or return the value to them.

Regarding the ruling on distributing internet services, it is not permissible to assist anyone who uses it for unlawful purposes by providing this service.
