What is the ruling on giving in charity the interest earned on money deposited in an Islamic bank?

The questioner : I deposited money in an Islamic bank, and after about four years, meaning to clear my conscience, I want to give away the excess, which is five hundred dollars. Is it permissible for me to give it to my sister so she can visit the House of Allah, since she has never visited it before?

The Shaykh : There is no harm in giving it to your sister so that she can perform the obligatory Hajj.

The questioner : Or an 'Umrah is possible.

The Shaykh : Or an 'Umrah, or the obligatory 'Umrah.
