What is the ruling on trading in music tapes and renting films that contain indecent scenes?

It is forbidden to rent or sell music tapes that contain music, or are performed by women, or include lyrics that invite vice; because when Allah forbids something, He also forbids its price. It is also forbidden to rent video films that contain images of unveiled women, or invite debauchery and music, or corrupt beliefs and morals, as this is considered aiding in sin and aggression.
