What is the ruling on listening to a chant in which the reciter repeatedly swears by Allah?

Swearing by Allah is not in itself an evil that necessitates abandoning listening to the anthem, nor is the repetition of the oath. Although it is better to avoid it unless there is a benefit, excessive swearing is disliked for the one who swears, not for the listener. If the anthem is free from evils like musical instruments, then there is no harm in listening to it.
