The Mufti says that it is permissible for us (a Muslim transport company) to transport electrical equipment for a cinema.

Answer

A cinema is a 100% haraam institution. How can it ever be permissible to aid such an immoral haraam institution? Will it be permissible to transport electrical equipment to a brothel? This is such a simple issue which every layman with healthy Imaan can understand. One does not need to be qualified in Knowledge for understanding this prohibition. Regarding such simple issues, Rasulullah (sallallahu alayhi wasallam) ordered Muslims: "Seek a fatwa from your heart."
