Silent partner in a cake shop which sells a little bit of non halal chicken

ASAK Wr Wb

I’m a full time software engineer and planning to open a cake shop as a side hustle. I cannot actively be a part of the business so I will be a silent partner with a non muslim friend. I will be making 100% investment though. Now the cake shop has some chicken patties that could be non halal although the franchise says its halal. Does it make me a sinner being part of a business that sells a little bit of non halal? There is no way to definitely prove that the chicken is halal.

Wasalam wr wb

May Allah bless you.

Sorry but what do you mean by the “franchise says its halal”?
