قَصْرُ الْمَوْصُوفِ عَلَى الصِّفَةِ
Restricting a subject to an attribute.
Attribute-to-subject qasr confines a quality or state to one subject. Subject-to-attribute qasr confines the subject to a stated quality among the attributes under discussion.
Do not confuse this with the separate contrast between real and relative qasr. The first distinction identifies the direction of exclusivity; the second specifies the domain within which the exclusivity is asserted.
