This is a a basic Arabic Grammar book for absolute beginners. Ilm-us-sarf or word morphology is the first step in learning Arabic. It is the science of word origins. The word Sarf has many meanings but as applied to Arabic grammar, is defined as changing of a root word into different forms to create an intended meaning. As you will learn in this book, 99% of Arabic words start from a three-alphabet root word, which is then changed into different forms to create different meanings. These rotations of the root word are called تَصْريْفٌ tas-reef or inflections. Prophet Sallal-lahu Alaihi Wa Sallam asked his Ummah to learn Arabic because it is the language of the Qur'an, it is his language and it is the language of the people of Jannah. Also, from the words of Imam Shaa-fai, knowledge is what is useful, not what is memorized.
