The book is the last in the series on the history of the Prophets of Allah. This book contains the lives of Prophets Zakariya, 'Isa, Yahya and Muhammad (may peace and blessings be upon all of them!). Children learn that all of the prophets brought Allah's message - Islam - to the people of the earth and the last one of them was the Prophet Muhammad (peace be upon him and his family!), and the final revealed book is the Qur'an, forever here to guide us.
