Assalāmu ʿalaykum, a friend of minewas offered a setter role for an Amazon dropshipping coaching company. They receive payment from customers first, then purchase from suppliers who ship directly. Is this model permissible? And is it allowed for me to sell their coaching? JazakAllahu khayran.

Ustadh AbdulAziz al-Haqqan

This is forbidden, what is allowed is if they give them permission to sell on their behalf, so they are middlemen.
