there is no concept of valentine day in islam at all....anybody that justifies it or tries to justify is totally wrong from all aspects of islam...that is not da day of love..it is simply a day to spread vulgarity in society and every body knows the outcome of this day...Only vulgarity spreads nothing else..the money we spend on flowers and gifts,we can better use it for poor patients,poor people and for handicapped people...

the sainst and soofis advocated love and peace not only co religious but for the entire humanity BUT THEY DID NOT SPREAD VULGARITY AND DID NOT INTRODUCE ANYTHING THAT CAUSED VULGARITY.
khair i know some people will not agree...
may Allah bless us...
