Assalamualaykum, What is the ruling on doing business with a person who is a Qadiani/Ahmadi. Also are they worse than regular non muslims because they claim to be muslims while they are not. JazakAllah Khair.

Ustadh AbdulAziz al-Haqqan

You can even do business with disbelievers as long as it doesn't contain something that is forbidden.
