salam alykum, My family we have our own business. its a slaughter house for poultry mainley chicken. usually a customer walks in picks the animal they want, it gets weight in front of them, they pay and then we slaughter the animal(halal) and then it gets proccessed and cleaned before it gets handed to them. but sometimes some poeple usually christians and other non-muslims that come to our business request to take the animal live without proccessing. are we responsibile on what the do to the animal since we are the ones that sold it to them. maybe they don't kill it the proper way, or maybe they cook it with the blood or use it for magic or something. are we held accountable to this, since all we did was sell the animal to them?
thank salam alykum

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

It is permissible for you to sell live chickens to people who wants it alive and you are not sinful if they use it in an unlawful manner because at the time of the Prophet the Muslims used to deal with the non-Muslims and sell to them animals without anyone condemning or disapproving that while they know that they eat dead meat and blood.

Allaah Knows best.
