According to search-discovered classical Islamic scholarship, 'rules' in Islam are encapsulated by the term 'Ahkam' (plural of 'hukm'), which refers to the divine commandments and legal rulings derived from the Quran and Sunnah. These rules form the basis of Sharia (divine law) and are interpreted through the methodology of fiqh (Islamic jurisprudence). As detailed by classical jurists, all human actions are classified into five categories of rules (al-Ahkam al-Khamsa): Fard (obligatory), Mustahabb (recommended), Mubah (permissible), Makruh (disliked), and Haram (forbidden). This comprehensive framework provides a moral and legal compass for Muslims, guiding them in all aspects of life, from worship to social interactions. Quran 5:2 serves as a powerful example of divine rules, establishing the sanctity of sacred rites and months, and promoting the foundational principle of cooperating in righteousness and piety while abstaining from sin and transgression.
