Encyclopaedia of Prophet Muhammad’s Teachings (Prophet’s Teaching and Women and Marital Relations) [PDF ebook] 

Islam is the complete code of life. It addresses issues, pertaining to almost every walk of life. Polity, economy, society, family, education human rights, self and national defence, inheritance, science, philosophy, religion spirituality, moral values, communal harmony etc. In fact, not a single subject has been spared, which does not find mention in Holy Quran and Traditions of Prophet Muhammad (Pbuh). Prophets teachings are all based on the Divine Revelations, made by Allah, the Exalted, through the medium of archangel Jibrael from time to time. The first revelation was made in the cave of Hira, when the Prophet (Pbuh) had completed four decades of his life. The cave event is, in fact, the manifestation and systematic declaration of the prophethood, which he had been endowed since birth. Completion of forty years of age is the time, when as a principle, prophethood is systematically declared and pronounced. Since the Prophet (Pbuh) was not formally literate, he never said anything on his own. Select criteria helped in sorting out his sayings, with authenticity and genuineness from amongst a plethora of mix sayings. Finally, about one lakh and fifty thousand sayings were sorted out, which have been collected into six books, based on Prophets teachings. Encyclopaedia of Prophet Muhammads Teachings is a multi-volume work, based on research and meticulous findings. Comprehensive, extensive exclusive and holistic, as it is, it must create an urge in all quarters of Islamic scholars to possess it.
