تَزَوَّجْتُ
I have married.
شَهْرًا
For one month.
The verb on its own conveys marriage in its ordinary sense. An expressly stated limited duration supplies further explanation and changes the classification of the supposed contract. Within this Hanafi legal-theory discussion, a time-limited union is treated as temporary marriage rather than a valid continuing nikāḥ.
The lexical sense of marriage, the qualification added to it, and the legal validity of the resulting contract must be considered separately. An explicit time limit cannot simply be ignored.
