Present modest work, namely, Historic Role of Islam, a comprehensive book is an effort for undertaking Islamic Studies in nutshell, authentically. I believe, it would prove to be valuable for the scholars, researchers, academics, students and general readers, alike. Enlightening comments and wise suggestions are heartily solicited and a warm response is awaited from concerned circles. Expectedly, this meritorious work would prove its worth. I thank Almighty for the accomplishment of this job.
