Brother, we really appreciate your forwarding this question to us, and we commend your keenness on getting yourself well-acquainted with the teachings of Islam. May Allah help us all keep firm on the Right Path, Amen!

As Muslims, we are required to love one another and to wish and inculcate love among people regardless of their color, race, religion, or identity. However, this does not mean dissolving our identity or blindly copying and imitating others' traditions and practices. Islam goes against celebrating Valentine's Day because commemorating that day is an innovation or bid`ah that has no religious backing, let alone the unlawful practices done during it that Muslims should not take part in.

In her response to your question, the Muslim scholar and da`iyah Zienab Mostafa states the following:

Thank you for this important question. It is unfortunate that many Muslims tend to copy and imitate others without understanding the backgrounds. Muslims must not dissolve the marked features of their identity. Muslims are only allowed to celebrate `Eid Al-Fitr and `Eid Al-Adha. Adding other days to the importance of `Eid is completely unacceptable and a blind imitation to un-Islamic traditions. We are cautioned against blindly following others. We should copy people in doing what is good and right, without compromising our faith. We should feel proud of our Islamic way of life.
