What is the ruling on visiting the home of a grandmother who tampers with the electricity meter to lower the consumption value?

Manipulating the electricity meter to reduce the bill amount is a form of cheating, deception, and consuming unlawful earnings, and it is not permissible to do so. However, this manipulation does not necessitate forbidding visits to the grandmother's house. Instead, those who manipulate the meter should be advised and reminded of the impermissibility of their actions.
