Islam has given the world a new and a rich civilisation. The Arabs, among all the great nations of the world have contributed to building of human civilisation, perhaps, have wielded the sword and pen with equal might and success over the centuries. The success achieved by them in intellectual areas is at par with their success in the battlefield. Teachings of the Holy Prophet infused a spirit of civility, culture, piety, justice and forbearance into a savage race and inspired their hearts with love of knowledge. The teachings propagated by the Holy Prophet of Islam knitted together the warring tribes of Arab into brotherhood, thus forming an irresistible force which swept over the whole of the world, weeding out corruption and evils wherever they went, founded a wealthier and a stable society based on equality, fraternity and justice. The nomadic Arabs who rose from the desert tents, founded, in a remarkable short time, the mightiest empire of the medieval period, which stretched from the shores of the Atlantic in the west to the highlands of Palmir in the east. Infect, they brought about the greatest revolution in the history of mankind-a revolution which embraced almost all branches of human activity. The present work touches upon all the aspects of Islam. Beginning with evolution, struggle, fundamentals of Islam, values, polity and concluding at the present state of Islamic society, thus making this a comprehensive study of civilisation in Islam. The book also presents the critical and comparative review and analysis of the faith. The author is confident enough that the present word will give a clear vision to its readers about the civilisation of Islam, with its remarkable historical background.
