Naats, nazams and nasheeds

Q: Is it permissible to listen to anaasheed, nazms etc if it does not have any musical instrument involved and follows the rules of Shar'iah i.e. no singing by women. Also if it is not used for entertainment/pleasure and is not interfering in anyway with our ma'mulaat or daily routine?

Saying "Khuda Haafiz"

Q: What is the ruling regarding saying "Khuda Haafiz" when departing from a meeting? I know that it is best to say "Assalamu Alaykum", but since "Khuda Haafiz" also has a good meaning, would it at least be better than saying "Goodbye"?
