Q: Is it haraam to use Facebook?
A. If Facebook is used to communicate with the opposite sex then this is Haraam. It is not permissible for a man to have ANY contact with a non-Mahram female, or a female to have contact with a non-Mahram male, be it telephonic, via sms, or mixit or facebook messaging, unless the communication is strictly business. To do so is totally Haraam and is Zina of the fingers (typing out messages to a non-Mahram woman or a non-Mahram man) just as it is Zina of the tongue to speak to him or her and Zina of the hands to touch and so forth.
Secondly, Islam teaches that any act that leads to sin or becomes the stepping stone towards sin is also sinful and must be avoided. In fact, most men share crude and rude messages with women over facebook and mixit, but because it is easy to cover their dirty tracks, they lie and say ‘we are just communicating for fun’. This is their idea of fun, but Shari’ah condemns it.
If these factors are absent then it will be permissible to use facebook as long as the contents of the communication are permissible
There are a few common practices among Facebook users that are also Haraam: spreading rumours about others; making Gheebat; exposing the faults of others; insulting others and hiding behind false names and identities; posting photographs;
If all these evils are avoided and people use it for lawful reasons or for Deeni purposes like Da’wah or answering Islamic questions by qualified Ulema, then the use of Facebook will be permissible.
Allah Ta’aala knows best.
