These are: Shahadah, the establishment of prayer (Salah), the payment of Zakah (paying the poor due), the Hajj (pilgrimage to Makkah and Sawm Ramadan (fasting the month of Ramadan).

Due to the pitiful state which the Ummah of Muhammad (may God praise him) is in, due to the lack of knowledge of Muslims about their religion, and due to the high regard which some Muslims hold for Western thought and culture, we see that a hideous practice which contradicts the very principles of chastity and honor in Islam has crept into many Muslim societies. Many people don't realize the origins and consequences of this shameful celebration, but rather blindly follow its rites and customs to be "closer" to the West, not thinking of the sin and displeasure they are earning from Allah.This Book study the ruling concerning this celebration and statements of scholars in this regard.
