How is Valentine's Day in Islam ?

Hhm...how do you celebrate the Valentine's Day? It's celebrated by almost all of people in the world on 14th February. From people in Europe until south east Asia. They give their dates a gift (such as chocolate or flowers) to show their love. The color as symbol of love, pink, is decorating the places on Valentine's day.
Now, how about muslim who has some laws in life? It's unallowed of course. All muslims haven't to celebrate Valentine's day, because it doesn't come from Islam. Allah SWT said :
“And whoever seeks a religion other than Islam, it will never be accepted of him, and in the Hereafter he will be one of the losers" [Aal ‘Imraan 3:85]
The Valentine's day came from The Old Rome culture, which the people are adorers of God (such as God Zeus, Hera, and Lupercus). On 13-14th of Februari the men did some rituals. One of them choose one of young girls in Rome to be his date for a year. Of course to have fun and do free sex. Na'udzubillahi min dzalik.
The Prophet (peace and blessings of Allah be upon him) told us that groups of his ummah would follow the enemies of Allah in some of their rituals and customs, as it says in the hadeeth of Abu Sa’eed al-Khudri (may Allah be pleased with him), who narrated that the Prophet (peace and blessings of Allah be upon him) said: “You will certainly follow the ways of those who came before you, span by span, cubit by cubit, until even if they were to enter a lizard’s hole, you would follow them.” We said, “O Messenger of Allah, (do you mean) the Jews and Christians?” He said, “Who else? !” (Narrated by al-Bukhaari in al-I’tisaam bi’l-Kitaab wa’l-Sunnah, Baab Qawl al-Nabi (peace and blessings of Allah be upon him) La tattabi’unna Sanan man kaana qablakum, 8/151; and by Muslim in Kitaab al-‘Ilm, Baab Ittibaa’ Sanan al-Yahood wa’l-Nasaara, 4/ 2054)
That's why we have to say NO to Valentine's Day!
