This book, with it's striking black and red cover has gained a place on many a Muslim's bookshop over the last ten years or so. Regarding the cover, when I spoke to the designer's son, he noted that it was his favourite due to it's simplicity, and so it is, I find with the book.
From the outset the authour set's out his work in an organised fashion, listing Qur'anic quotes, Hadith (statments of the Prophet Muhammad, peace be upon him) and various other narrations in logicla order. After narratating various hair raising stories, he draws the book to a beautiful conlusion,i.e. that to safeguard one'self from the evils present in the unseen, one must be firmly rooted in sacred knowledge and wisdom.
