The שולחן ערוך השלם (Shulchan Aruch HaShalem) is a renowned Jewish legal code written by Rabbi Yosef Karo. It consists of four parts, each focusing on different aspects of Jewish law and practice.

The first part, אורח חיים (Orach Chaim), covers the daily laws and rituals, including waking up in the morning, wearing tzitzit and tefillin, prayer, Shabbat, holidays, and more.

The second part, יורה דעה (Yoreh De'ah), deals with laws pertaining to kosher slaughter, permissible and forbidden foods, laws of purity, laws of interest, laws of vows, commandments that can be fulfilled outside of the land of Israel even in exile, and more.

The third part, אבן העזר (Even HaEzer), focuses on laws related to marriage and divorce, and the laws of relationships between spouses. The name of this section is derived from the verse in Genesis 2:18, "I will make him a helper corresponding to him."

The fourth part, חושן משפט (Choshen Mishpat), covers laws pertaining to judges, monetary matters, laws of the court system, civil and criminal law.
