I have a new project as a website developer to build a website for a restaurant supplies business.
They sell everything you need for a restaurant (ex: knives, uniforms, shelves, machines)
I noticed they also sell things like a wine fridge (empty) and bar equipment like a shaker.
Note: they only have a handful of products that might be used for haram (ex: a wine fridge) but it can also be used for halal (ex: to store non alcoholic beverages)
I found online source here that if the business doesn't specialise in haram (ex: they specialise in selling alcohol), it is allowed:
But they don't have any specific reference.
Not sure what's the ruling here, please help.
