Shaikh Abdurrahman ibn Nasir al-Barrak hafidhuhallah was asked:

Question:

Amir from Canada says: Assalamu Alaykum wa rahmatullahi wa baraktuhu. May Allah bless you our Virtuous Shaikh and may Allah make you beneficial. I work in an electronic store like a seller and customers come to buy what they want. Then most of them pay for their purchases with the usurious visa card. So what is the ruling on this work of mine?

Answer:

You do not busy with this. The ruling of the visa follows them, not you. Take your entitlement or what they send you. The purpose/intent which is apparent to me is that there is no blame on you for that. Yes.
