Al-Mughni's treatment of ritual law sets a standard of thoroughness that few works have matched. The chapters on tahara examine every scenario from the major impurity requiring ghusl to the minor impurity requiring wudu, addressing unusual cases such as the rulings for the sick, the traveler, and the person who cannot find water. The chapters on prayer cover obligatory prayers, congregational prayer, the Friday prayer, the two Eid prayers, and the prayer of the traveler, with detailed attention to the conditions, pillars, and recommended elements of each. Ibn Qudamah adduces extensive hadith evidence for every ruling and engages critically with the transmissions cited by other schools.

In commercial law, al-Mughni is particularly celebrated for its treatment of contracts. The chapters on bay' (sale), ijara (lease), musharakah (partnership), mudarabah (profit-sharing investment), and waqf (endowment) present the Hanbali positions with their evidential bases, compare them to the other schools, and work through the complex edge cases that a practicing jurist would need to resolve. The treatment of riba (interest/usury) is especially detailed, examining the various forms of prohibited exchange and the conditions under which sale becomes impermissible.

Family law chapters address marriage, its conditions and pillars, the rights of spouses, divorce in its various forms, custody of children, and the rules of inheritance. These chapters are among the most practically important in the work, as questions of marriage and divorce formed a large share of the cases that came before medieval Islamic courts. Ibn Qudamah treats them with both legal precision and awareness of their human significance.

The treatment of jihad, criminal law, and the rules of war reflects the military realities of Ibn Qudamah's time. He addresses rules for combatants, non-combatants, treatment of prisoners, and the distribution of spoils. Throughout the work, the recurring theme is the grounding of Hanbali law in the Quran, the verified Sunnah, and the practice of the Companions.
