Working for music/video sites

I own a web development business and build websites for foreign clients. I wanted to know IS IT ALLOWED to make a website for online video store where people could come and select movies of their choice? Please please help me regarding this, its effecting me as I get confused when some client approaches and ask for some related services like video or music sites.

Walaikumassalam wa rahmatullah,

The whole Shariah has been given to us in order to promote the good of humanity.

Based on explicit texts of the Qur'an and the Sunna, the scholars of Sunni Islam concur that it is not allowed to assist others in sinful activity.

Allah commanded us:

5.002               ... Help you one another unto righteousness and pious duty. Help not one another unto sin and transgression, but keep your duty to Allah. Lo! Allah is severe in punishment.

And:

016.090           Lo! Allah enjoins justice and kindness, and giving to kinsfolk, and forbids lewdness and abomination and wickedness. He exhorts you in order that you may take heed.

It says in Majallat al-Ahkam al-`Adliyya:

“Item 34:       That which is impermissible to take is impermissible to give.”

And Allah alone gives success.

Wassalam,
