السلام عليكم و رحمة الله و بركاته احسن الله إليكم شيخ Can you buy an online receiver device that has all movies/shows even up to date from someone which you doubt or is most likely that he pirated them? What if you already bought it unknowingly?

Ustadh AbdulAziz al-Haqqan

Not allowed, even if it wasnt pirated as they contain that which is forbidden.
