The Festival of Love was one of the festivals of the pagan Romans, when paganism was the prevalent religion of the Romans more than seventeen centuries ago. In the pagan Roman concept, it was an expression of “spiritual love”. There were myths associated with this pagan festival of the Romans, which persisted with their Christian heirs. Among the most famous of these myths was the Roman belief that Romulus, the founder of Rome, was suckled one day by a she-wolf, which gave him strength and wisdom.
The Romans used to celebrate this event in mid-February each year with a big festival. One of the rituals of this festival was the sacrifice of a dog and a goat. Two strong and muscular youths would daub the blood of the dog and goat onto their bodies, then they would wash the blood away with milk. After that there would be a great parade, with these two youths at its head, which would go about the streets. The two youths would have pieces of leather with which they would hit everyone who crossed their path. The Roman women would welcome these blows, because they believed that they could prevent or cure infertility.
Indeed, Islam is the religion of altruism, true love, and cooperation on that which is good and righteous. We implore Allah Almighty to gather us together under the umbrella of His All-encompassing Mercy, and to unite us together as one man. Allah Almighty says: (The believers are naught else than brothers. Therefore make peace between your brethren and observe your duty to Allah that haply ye may obtain mercy.) (Al-Hujurat 49: 10) Focusing more on the question in point, I can say that there are forms of expressing love that are religiously acceptable, while there are others that are not religiously acceptable. Among the forms of love that are religiously acceptable are those that include the love for Prophets and Messengers. It stands to reason that the love for Allah, and His Messenger Muhammad (peace and blessings be upon him) should have the top priority over all other forms of love. Islam does recognize happy occasions that bring people closer to one another, and add spice to their lives. However, Islam goes against blindly imitating the West regarding a special occasion such as Valentine’s Day. Hence, commemorating that special day known as the Valentine’s Day is an innovation or bid`ah that has no religious backing. Every innovation of that kind is rejected, as far as Islam is concerned. Islam requires all Muslims to love one another all over the whole year, and reducing the whole year to a single day is totally rejected.
