Book excerpt: The essential introduction to Islam by a leading expert Hardly a day goes by without mention of Islam. And yet, for most people, and in much of the world, Islam remains a little-known religion. Whether the issue is violence, terrorism, women's rights or slavery, Muslims are today expected to provide answers and to justify what Islam is - or is not. But little opportunity exists, either in the media or in society as a whole, to describe Islam: precisely the question this short and extremely accessible book sets out to answer. In simple, direct language it will introduce readers to Islam, to its spirituality, its principles, its rituals, its diversity and its evolution.
