This is the first volume from this series, which deals with the life of Abū Bakr as-Șiddīq, the first of the Four Rightly-Guided Caliphs. No other person in the History of Islam can be compared to him when it comes to truthfulness, insight into Islamic teachings and devotion to Allah and His Messenger (S). He was outstanding and unique in his commitment, sincerity, and whole-hearted support and assistance to the Prophet.
