ANSWER:

Buying such bones of disbelievers for studying purposes is permissible.

Selling it however is not and one should give it as a gift to other needy students.

As a medical student, We have to buy Human bones for 30-40k BD taka. After a exam, We sell bones to juniors for as much money as we buy them. So there is no profit at all. It’s not like business. It’s just handing over the bones to juniors for the same money. So,is it permissible to sell the bones and take the same money?
