In 1990 the Watchtower Society published Mankind's Search for God, a hardcover book which had a 22-page chapter on Islam - The Way to God by Submission. This includes discussion on the Five Pillars of Belief, the Five Pillars of Observance, the Qu'ran, the Hadith (Sunnah), Shariah law, the spread of Islam, shahadah(confession of faith) and more.
