This book is a concise and immensely satisfying historical account of the first four caliphs of Islam, Hadhrat Abu Bakr, Umar, Uthman and Ali (R.A.), who because of their rectitude, became known as the ‘Rightly Guided Caliphs” (may Allah be pleased with them). Also, includes a Section on the fifth Caliph Hasan Ibn Ali (R.A.).
