If the one who takes interest says, "I will not leave the interest in the bank because it is aiding them in doing wrong"?

The questioner : If he says that if he leaves this interest in the banks, they will use it in sin.

The Shaykh : Who said, first of all, did this interest enter his ownership?

The questioner : No.

The Shaykh : So what is it, then?

The questioner : But the bank believes that it belongs to this man.

The Shaykh : But legally, it is not mine, so it cannot be said that I am aiding in a sin. For example, we say that it did not enter my ownership in the first place, and by the command of Allah (Mighty and Majestic), it is not permissible for me to take it. And if the Prophet (peace and blessings be upon him) invalidated the taking of interest that had been contracted in the pre-Islamic age of ignorance before the laws were revealed, how is it with this? And this matter, even though some people are lenient in it and say, "Take it and give it in charity," that is a mistake. If we were to rule according to what the evidence requires, in my opinion, that would be a way to get rid of the banks, because if they knew that, for example, what they call interest—millions, meaning it is not a thousand, but millions—if they knew that it would go away, they would have to establish Islamic banks and benefit from them.
