The Standing Committee was asked: Some people celebrate Valentine’s Day on the fourteenth of February every year. They exchange gifts of red roses and wear red clothes and congratulate one another. Some bakeries make red coloured sweets and draw hearts on them, and some stores advertise products that are especially for this day. What is your opinion on the following: 
1-     Celebrating this day
2-     Buying things from the stores on this day
3-     Storekeepers who are not celebrating it selling things that may be given as gifts to people who are celebrating it? 
They replied: 
The clear evidence of the Qur’aan and Sunnah – and the consensus of the early generations of this ummah – indicates that there are only two festivals in Islam: Eid al-Fitr and Eid al-Adha. Any other festivals that have to do with a person, a group, an event or anything else are innovated festivals, which it is not permissible for Muslims to observe, approve of or express joy on those occasions, or to help others to celebrate them in any way, because that is transgressing the sacred limits of Allaah, and whoever transgresses the sacred limits of Allaah has wronged himself. If the fabricated festival is also a festival of the kuffaar, then the sin is even greater, because this is imitating them and it is a kind of taking them as close friends, and Allaah has forbidden the believers to imitate them and take them as close friends in His Holy Book. And it is proven that the Prophet (peace and blessings of Allaah be upon him) said: “Whoever imitates a people is one of them.” Valentine’s Day comes under this heading because it is an idolatrous Christian festival, so it is not permissible for a Muslim who believes in Allaah and the Last Day to observe it or approve of it or congratulate people on it. Rather he has to ignore it and avoid it, in obedience to Allaah and His Messenger, and so as to keep away from the causes that incur the wrath and punishment of Allaah. It is also haraam for the Muslim to help people to celebrate this or any other haraam festival by supplying any kind of food or drink, or buying or selling or manufacturing or giving or advertising etc., because all of that is cooperating in sin and transgression and is disobedience towards Allaah and His Messenger (peace and blessings of Allaah be upon him). Allaah says (interpretation of the meaning): 
“Help you one another in Al‑Birr and At‑Taqwa (virtue, righteousness and piety); but do not help one another in sin and transgression. And fear Allaah. Verily, Allaah is Severe in punishment”
[al-Maa’idah 5:2] 
The Muslim must adhere to the Book of Allaah and the Sunnah in all his affairs, especially at times of fitnah when evil is widespread. He should be smart and avoid falling into the misguidance of those who have earned Allaah’s anger and who have gone astray, and the evildoers who have no fear of Allaah and who do not have any pride in being Muslims. The Muslim must turn to Allaah and seek His guidance and remain steadfast in following it, for there is no Guide except Allaah and no one can make a person steadfast but Him. And Allaah is the source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
