Is working in an internet cafe permissible or forbidden, knowing that the nature of the work usually involves paying water and electricity bills, but sometimes customers frequent it to browse inappropriate websites or engage in chats and listen to songs? What is the ruling of Islamic law in this case, given the urgent need for work and to provide for the family?

The internet is a double-edged sword that can be used for good or evil. The owner of the cafe or the employee working there is responsible for its use. It is not permissible to provide internet service to someone known to be using it for unlawful purposes, unless this is not apparent. If, however, they subsequently use it for an act of disobedience, then they must be commanded to do good and forbidden from evil. If they persist, the service must be cut off. The questioner must observe these matters in their work.
