Disposing of song tapes after repenting of listening to songs

Q 1: I used to listen to songs, but I repented, praise be to Allah. However, I still have some song tapes that belong to some of my colleagues. Should I burn them, or return them to their owners?

A: You should erase the songs from the tapes and make use of these tapes by recording Qur'an, lectures, or any useful content on them instead. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
