Assalaam o Alaikum The question is: Is the business of providing Internet Service justified as the customer could use the internet for some Haraam purpose like surfing porn sites.
Answer:
(Fatwa: 971/898=D/1429)
If the internet is used for permissible purposes then providing internet services is lawful. One should not personally involve in unlawful things, if the costumer makes illegal use of it then he will be sinner and responsible for the same.
