Q: Is it permissible to sell tickets for basketball and football events? Some say yes and i read some say no. Can you tell me why not? (email)

A: Permissible.

It is however frowned upon (makrooh) to sell tickets of events that promote alcohol consumption, inappropriate attire, display of humans as objects, violence, promotion of abusive language, etc.

Best to deal in products that represents ones core values.

Allah Certainly Knows Best.
