World of Great Muslims are those, who have made an impact on the world civilization, world culture and style of life. Most of them have left their lasting footprints in several ages and eras. From the day first down to the present hour, men of exceptional qualities came in this world, who held the banner of Islam high and promoted the cause thereof, professedly and professionally. Prophets and Messengers apart, men of astounding knowledge and insight of Islam contributed their best to the making of the world. In fact, sons of Islam have changed the world scenario, to a great extent: Followers of Islam or Muslims have scaled new and newer heights in all areas. For this purpose, they offered wholehearted sacrifices of their wealth and assets and even lives and eventually got their names recorded in the pages of history. Short biographies are now in vogue, as readers have little time to devote to lengthy details, in huge books. Hence this mini-encyclopaedia of biographies of great Muslims — men and women, in all walks of life. This voluminous compilation is an adventurous academic endeavour, in its own right. This work is destined to be acknowledged, by libraries and all academic circles. This is an asset for all scholars, researchers, students and general readers, alike.
