«ومناهي الشرع ثلاثة أقسام: الحرام، والمكروه كراهة تحريم، والمكروه كراهة تنزيه»
The law's negative directions fall into three groups: haram, makruh tahrimi and makruh tanzihi.
Each involves some degree of discouragement or prohibition, but they differ in the strength of the demand and the standing of the evidence. Calling an act “disliked” cannot by itself tell us whether the act is gravely forbidden or merely preferable to avoid.
Notice how conclusive versus non-conclusive proof and the effects of violation distinguish these categories.
