Most folks these days refer to the celebration of romance on February 14th as simply Valentines Day, but it’s actually the feast day of St. Valentine. I”m not going to bore you with the real story of Valentine, but I will be telling you that there was a Fatwa, or a serious religious warning against participating in Valentines activities for Muslims.
It seems they think that celebrating St. Valentines Day reeks of Christianity, which is bad. It also encourages premarital relationships and too much physical closeness for unmarried people.
By the way, Yoga is also considered dangerous among Muslims.
