A book in Russian focuses that the Prophet's Companions (may Allah be pleased with them) are the most purified and knowledgeable ones after him. A nation's honor is related to their elite, the Prophet's Companions, such as the four Caliphs: Abu Bakr, Omar, Othman, and Ali (may Allah be pleased with them). This book tries to present something from their biographies to take them as our examples.
