Salaam,starting a business importing all my products in from China as it’s cheap,is this permissible or am I sinful as China is at war with Muslims
May Allah bless you.
This sort of question cannot be answered with a simple yes or no.
We live in a globalised world and there are many things to take into consideration.
As for your business, do what you are comfortable with. Unless if you have proof that by buying from your supplier, you are definitely hurting Muslims, then it would not be permissible to buy from China.
And Allah knows best!
