Shaykh Uthaymeen said, “Celebrating the likes of Valentine’s day is not permissible, for the following reasons:
Firstly, this festival has no precedence in our Shariah.
Secondly, it calls to people to having love and infatuation (in an impermissible manner).
Thirdly, it calls people to have their hearts being occupied with trivial issues which contradicts the guidance of the Salaf as-Saalih (the righteous predecessors).
Based on this, it is not permissible for us to assist with this day or any of the symbolisms connected to this festival, whether it is from the food and drinks they share or to resemble them in clothing or to follow anything that will resemble or imitate them.
Therefore, it is obligatory upon the Muslim for him to be firm in his religion and for him/her not to be blind and follow this corrupt.
I ask Allaah, the Most High, to protect the Muslims from all types of trials and tribulations, that which is apparent or hidden, and that He Assists us in our tests with His Assistance and Guidance.”
