A man hesitates to visit his brother and eat his food because he works in a bank; is his action correct?

The questioner : There is a man whose brother works in an interest-based bank, and each of them lives alone in his own residence. This brother of ours, who does not work in the bank, hesitates to go visit his brother, and naturally, his brother provides him with food. What is the ruling on going there?

The Shaykh : If this visit is not accompanied by reminding and advising this brother who works in the bank, then such mixing and eating together should not be done. However, if he reminds his brother from time to time, then there is no objection in this case to eating his food and drinking his drink.

The questioner : I mean, the reminder does not have to happen every time he visits?

The Shaykh : No, but it should be done intermittently.

The questioner: Yes.
