وَهُوَ حَقِيقِيٌّ وَغَيْرُ حَقِيقِيٍّ
Qasr is real or non-real (relative).
Real qasr purports to exclude all alternatives within the attribute or subject as stated, rather than only a selection of alternatives relevant to a dispute.
Relative qasr excludes other subjects or qualities only in comparison with a particular set. “Real” in this taxonomy does not simply mean “a true statement”; it identifies the asserted scope of exclusion, not the truthfulness of any sentence.
