If a husband asks his wife to dance for him, must she obey him?

There is no harm in a woman dancing for her husband with the intention of showing affection and preventing him from looking at forbidden things, provided certain conditions are met: that none of the children are present, that no musical instruments are used, and that no forbidden films or pictures are watched to learn how to dance. Sheikh Muhammad ibn Salih al-Uthaymeen and Sheikh Muhammad Nasir al-Din al-Albani are of the opinion that this is permissible because it increases desire between the spouses and does not fall under the blameworthy imitation of dancers if it is only between the husband and wife.
