Synopsis In the history of mankind, Hadrat Umar occupies a unique position. He is the greatest of all the names that have come in the history as great conquerors, empire-builders, administrators and statesmen. He established Arabia as world-power. He set standards of republican democratic behaviour which have not been surpassed so far. He was the Head of the largest State of the world, but he lived the life of a common man. His greatness was acknowledged by the Holy Prophet when he said that if there were to be any Prophet after him it would have been Hadrat Umar. Verily Hadrat Umar was not a prophet, but he did things which a prophet have done. He was the man of strong character and strong will who made history. It is a matter of great regret that no much authentic books are available in English on him. So the author has ponder over the matter and produced this biography of Hadrat Umar. He analysed all the events in detail and evaluated him with great honour and honesty. Its language is very simple and comprehensive. This book will be useful for the teachers, students and other inquisitive readers.
