Question :
I work for an internet and power cables company. This company has agreed to install cables to a Riba-based bank. Is it permissible that I work in this project or not?
The Answer :
Praise be to Allah the Lord of the Worlds.
Works done in favor of Riba-based banks and help in or facilitate their usurious transactions are forbidden, and since you (Asker) don`t deliver such works then there is no blame on you. And Allah the Almighty knows best.
