I am a young married man. I used to buy tapes of songs, and I swore to divorce my wife if I bought song tapes. Now I want to buy religious tapes.

Praise
be to Allaah.

Praise your Lord for blessing you with guidance. The
one who repents from sin is like one who did not sin at all. Your vow
of divorce was related to song tapes, not all kinds of tapes. So go
ahead and buy religious tapes and listen to them, but do not buy the
tapes concerning which you made your vow of divorce.
