Muslims do not celebrate 25 December, 31 December and 1 January, it is also against Sunnah to congratulate and celebrate birthdays. Sheikh Saalih Al Fawzaan that ALLAH preserved him said: We will continue to tell the truth even if many people ignore that truth. To congratulate and celebrate birthdays, celebrate the New Year's Eve, has no basis in sunnah. Sheikh bin Baaz Rahimahullah was categorical: it is necessary to be excellent in sunnah so that all bidã'ates (innovations) are purged. Udu khulu fi silmi caffah (we have to get into Islam completely). Our passions and desires cannot be above sunnah and shariyah. Wala talssibul haq bil baatwil (You cannot mix truth with falsehood). Nabi Muhammad blessed be his name said: Whoever introduces an action, which is not part of the actions I have taken, this action will be rejected (i.e. this action has no formal validity or material validity in the light of Shariyah).
