This book is part four of the "Enter into Islam... Completely" series. It deals with the authentic Sunnah performing acts of worship during menses.

In this series, various issues which are of extreme importance to the Muslims, have been discussed. Today, a lot of these issues are underplayed or even affronted by many. When any of these issues is brought up, often, an objection is raised saying, "This is merely an issue of peel! Let us only deal with the important issues of the core!"

Classifying the teachings of Islam into "core" and "peel" is a bid'ah that affects the hearts of the common people in the most damaging way, and leads them to disparagement of many of the acts of worship and traits of the Islamic character, thus approving wrong acts and rejecting good ones based on a crooked scale that they have developed.
