In the Name of Allaah, The Most Merciful, The Bestower of Mercy.
Imaam Muhammad Ibn Saaleh Al-Uthaymeen (rahimahullaah)
said:
Celebrating Valentine’s Day is impermissible due to [several] reasons:
Firstly: It is an innovated Eed [holiday]. It has no
basis in the Sharee’ah.
Secondly: It calls to passion and infatuation.
Thirdly: It is a means of preoccupying the heart with
the likes these insignificant affairs and it is in opposition to the guidance
of the Salafus Saaleh [The Pious Predecessors].
Therefore, it is impermissible to initiate anything on
this day [i.e. specifically on Valentine’s Day] related to [celebration],
whether it is foodstuffs, drinks, clothing, and exchanging gifts or other than
these [actions]. It is obligated on a Muslim to nobly [adhere to his (or her)]
religion and he [or she] should not be one who goes with the flow – following everyone
who calls to something.
