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.
