Islamic Spirituality is based upon the asumption that what appears to us mystery revelated itself as being God. The Qur'an is this revelation. The Qur'an Instructs us in the foundational importance of awareness of God and the proper response to God. The Sunnah (lifestyle or practice) of Muhammad expresses and exemplifies this Qur'anic wareness of and response to God within actual, historical phenomenal reality. This is the heart and foundation and raison d'etre of Islamic spirituality. Muhammad is considered to be a "walking Qur'an". Islamic spirituality fosters God-consciousness, called taqwa, in and through add daily activities in addition to activities we usually identify as 'spiritual" such as fasting and prayer. It shuns any extermes. Islamic spirituality is active in all four aspects of human experience. It thus avoids extremes of interiority and does not portray the physical or the social as being contra the spirtual.
