1. Is it permissible to learn dancing?
It is not allowed at all, as a matter of obligatory precaution.

2. Is it permissible to organize dance parties where each husband dances only with his own wife to the sound of soothing musical tunes, wearing dresses that are not indecent?
It is not allowed.

3. Is it permissible for women to dance in front of other women or for men to dance in front of other men in a gender-wise segregated gathering with or without music?
Dancing of women in front of women or dancing of men in front of men is problematic, as a matter of obligatory precaution, one must refrain from it. The rules governing music have already been discussed earlier.

4. Is it permissible for a wife to dance for her husband with music or without music?
It is allowed as long as dancing is not accompanied with haram music.

5. Some schools in the West make it obligatory that their male and female students learn dancing. This dancing is neither accompanied by the common song, nor is it for entertainment; it is part of the educational curriculum. So, is it haram for the parents to allow their sons and daughters to attend such classes?
Yes, if it contravenes the religious upbringing. Rather it is, based on obligatory precaution, forbidden absolutely, if the student has reached the age of maturity — except if he has a valid reason for approving of it; for example, if he follows a mujtahid who allows it. In the latter case, nothing prevents him from allowing his child to take part in [such activity].
