Q. Why is it not permissible to wear jeans? What is the ruling if it is worn just for the husband?
A. Jeans is the dress of fussaaq (depraved people). It is not permissible to emulate the fussaaq in their lewd dress styles. Furthermore, this tight fitting garment is also said to be harmful, physically. We have seen several reports of the harms to a person’s health in wearing this tight fitting outfit. Alas we had to mention this factor, whereas the spiritual harm ought to be sufficient deterrence for a Muslim to adopt abstention.
It is highly unbecoming of Muslim husbands to desire their wives to follow the fashion of the zaaniyahs who prowl the streets. This smacks strongly of fisq.
