وحرمة الفعل لا تنافي ترتب الأحكام
The prohibition of an act does not, by itself, prevent all legal consequences from following its occurrence.
In the example of intercourse during menstruation, the prohibition remains in force. Yet family-law questions arising afterward cannot be dismissed solely because the act was forbidden.
Consequences such as dower or waiting periods require their own conditions. The principle does not assert that every illicit sexual act always creates all the legal consequences of a valid marriage. It separates unlawfulness from the conditions of a particular legal effect.
