Alhamdullillaah. When the Prophet (Salallaahu Alayhi Salaam) sent his companions, Mu'adh ibn Jabal and Abu Musa (may Allaah be pleased with them both), to teach Islaam to the people of Yemen, he advised them, "Facilitate [the religious matters to people] and do not make [things] difficult." (Saheeh Bukhaaree & Muslim).With that idea in mind, The Book of Islaamic Lists is designed to facilitate learning via the compilation and organization of important lists related to Islaam, in-shaa'allaah. Lists can be important teaching tools. They are more succinct than paragraphs of prose, and are, therefore, easier to read. They can be read at random, and do not necessarily require extended reading time or sequential reading. Lists present main ideas in a logical order. Lists, in other words, can be very user-friendly.While the reading of full texts is both praiseworthy and highly encouraged, it is the author's hope that this humble book will not only enable more readers to have access to important concepts in Islaam, but also motivate them to read the seminal works, in-shaa'allaah.
