“The evidence in the Qur’aan and Sunnah indicates that celebrating birthdays is a kind of bid’ah or innovation in religion, which has no basis in the pure sharee’ah. It is not permitted to accept invitations to birthday celebrations, because this involves supporting and encouraging bid’ah. “Whoever does something that is a not part of this matter of ours (i.e., Islam) will have it rejected” (reported by Muslim in his Saheeh); and “The best of speech is the Book of Allaah and the best of guidance is the guidance of Muhammad (peace and blessings of Allaah be upon him). The most evil of things are those which have been newly invented (in religion), and every innovation is a going astray.” There are many other ahaadeeth that convey the same meaning.
Besides being bid’ah and having no basis in sharee’ah, these birthday celebrations also involve imitation of the Jews and Christians in their birthday celebrations. The Prophet (peace and blessings of Allaah be upon him) said, warning us against following their ways and traditions: “You would follow the ways of those who came before you step by step, to such an extent that if they were to enter a lizard’s hole, you would enter it too.” They said, “O Messenger of Allaah, (do you mean) the Jews and Christians?” He said, “Who else?” (Reported by al-Bukhaari and Muslim). The Prophet (peace and blessings of Allaah be upon him) also said: “Whoever imitates a people is one of them.”Fataawa Islamiyyah, 1/115
Ah, yes, BUT...
You are forgetting the “if it advances the cause of Islam in Dar al Harb, then it is permissible” principle of taqiya.
Even more deception is involved by setting a fixed date on the Infidel’s solar calendar, rather than using an Islamic lunar date.
This is just another attempt to make ignorant people believe that Islam is “just like” any other major religion that it is really NOTHING like at all.
