Undoubtedly, Imam al-Ghazali is the founder of the Maqasid Sharia knowledge framework. This is
marked by the work of Imam al-Ghazali in the 5th century entitled "al-Mustasfa min ‘Ilm al-Usul" and
"al-Mankhul min Ta’liqat al-Usul". Therefore, this study aims to determine the theory of Maqasid
Sharia according to Imam Al Ghazali and its application in the Compilation of Islamic Law (KHI) in
Indonesia. This study is based on a library research which is sourced directly from al-Ghazali’s books;
al-Mustasfa and al-Mankhul, as well as the Compilation of Islamic Law manuscript, particularly in
marriage chapter. The results of this study indicate that the Maqasid Sharia concept has been applied in
several cases in the marriage chapter, such as cases in marriage registration law of taklik talak and
pregnancy marriage. The categories of Maqasid Sharia used in the enforcement of these laws are
Maqsad ad-Daruriyyah namely Hifz ad- Din (protecting religion), Hifz an-Nafs (protecting soul), Hifz
al-Aql (Protecting intellect), Hifz an-Nasl (protecting lineage) and Hifz al-Mal (protecting property)
