Assalamu alaikum wa Rahmatullah
I have a small IT startup company and I am asked to develop a mobile app by which user can open account with the Bank. Note that the bank is operating in regular/traditional interest based system and the user has option to prohibit interest accumulation to his account.
My question is: will the income with this kind of software development be halal?
Jajak-Allahu Khairan.
