What is the meaning of a "religiously prohibited act" (al-mahzhūr ash-shar'ī)? Your prayers are sought.

The religiously prohibited (al-Mahdhur ash-Shar'i) according to theologists is that which the Sacred Law has forbidden, and it includes both the Haram (unlawful) and the Karahah Tahrim (reprehensible to the point of being almost unlawful). Thus, the prohibitions are the religiously forbidden acts for which the doer deserves punishment.
