DANCING. Arabic Raqs. Dancing is generally held to be unlawful, although it does not appear to be forbidden in either the Qur’an or the Traditions, but according to al Bukhari (Arabic ed., p. 135), the Prophet expressly permitted it on the day of the great festival. Those who hold it to be unlawful quote the following verse from the Qur’an Surah xvii 39 “Walk not proudly on the earth,” as a prohibition, although it does not seen to refer to the subject.
The Sufis make dancing a religious exercise, but the Sunni Muslims consider it unlawful. (Hidayatu ‘s-Sa’il, p. 107.)
