Our book, titled "The Jami Aldurar fi Alistilah Almutabar" was written with the aim of introducing Islamic sciences, their scholars, their scholarly heritage, their honorable biographies, and their distinguished students. It also seeks to shed light on recognized Islamic terminologies, including the obscure, unfamiliar, and eloquent terms—those which may pose a challenge to students of Islamic knowledge, particularly those taking their first steps in this field. The book categorizes Islamic sciences into six main sections: Qur’anic Sciences Hadith Sciences Islamic Creed (Aqeedah) Sciences Principles of Islamic Jurisprudence (Usul al-Fiqh) Islamic Jurisprudence (Fiqh) Islamic Ethics
