Is it permissible for a wife to listen to music and dance to it for her husband?

If the singing is free of musical instruments — except for the duff (hand drum) — and its lyrics are permissible, then there is no harm in dancing to its rhythm for one's husband. However, if its lyrics are forbidden, such as obscene flirtation, or if it is accompanied by musical instruments, then it is impermissible to listen to it, due to the Prophet's (peace be upon him) saying: "There will be among my nation people who will deem lawful Al-Hir (illegal sexual intercourse), silk, wine, and musical instruments."
