The book presents a life sketch of the Prophet Muhammad, his ancestors, Abraham and Ishmael, religious and social conditions that existed in Arabia at the time of his birth in Mecca in a family of merchants. His father passed away a few days before his birth. His mother mother mother died when he was about eight years old. Even at a young age he was devoted to prayers to God, fasting and meditation. He received the first divine call at the age of 40 years to invite all human beings to the path of righteousness. The divine revelations that he received in the years that followed were recorded in a book known as the Holy Quran, in his life time. He himself made the arrangement of chapters, Suras and verses of the Holy book as we see it today, without the slightest alteration in the text ever made by anyone in the past nearly 1500 years. Copies of the Quran were made immediately after his demise. His message, the religion of Islam, provides guidance to mankind in every possible aspect of human life. Apart from daily prayers, fasting in Ramadan, Hajj, charity and personal and communal piety, the Quran deals with social matters as well as Islamic laws. Three chapters are devoted to the decline of faith and its revival inaugurated by Mirza Ghulam Ahmad in the 1889.
