The book are compilations of lectures on various topics, with part 1 covers basic belief, ritual purity, ritual prayer, required charity (zakaa), fasting, haj and a few miscellaneous topics. Part 2 is more for the Muslim who needs to interact with non-Muslims. It tries to address issues of controversy among Muslims. It has a bit of sex education.
