My friend needs to take a loan of Indian rupees 1 million for business purposes but he believes paying interest on bank loan is haram

What is the alternative halal solution to take loan from the bank?

If there is no way and option other than taking an interest based loan from a bank then he can take with the niyyat (intention) that I will not pay the interest on the loan until I'm compelled to pay it by the bank through the law and ruling of the country for example.
That means he should keep the intention in his heart not to pay the interest except that he is compelled to do it and he shouldn't pay the interest with pleasure and wish but due to compulsion.
