What is the Sharia ruling on children using electrical appliances connected illegally to the electricity meter, and what should they do if their father refuses to reconnect them properly?

Your father's manipulation of the electricity meter and his unlawful appropriation of people's money are forbidden in Islamic law. This sin is even more severe because it involves public funds. The Prophet, peace and blessings be upon him, warned against this, saying: "Indeed, there are men who delve into the money of Allah without right, and for them is the Fire on the Day of Resurrection." Therefore, you must continue to advise and admonish him.

As for benefiting from stolen electricity: 1. If the electricity is entirely stolen, or the stolen portion can be clearly distinguished, then it is not permissible for you to benefit from the stolen part. You must strive to rectify the situation and restore the meter to its normal state. However, for those in need who are under the father's financial responsibility, it is permissible to benefit to the extent of their need, without extravagance, as most electricity companies are owned by public funds. 2. If the misappropriation of electricity is not distinguishable (such as slowing down the meter), then the prohibition is limited to the father, and there is no harm for the rest of the family to benefit from it, due to the mixing of the unlawful with the lawful and the difficulty of distinguishing between them.
