﴿حَيَاةٌ﴾
Life.
The noun ḥayātun appears indefinite. In context, the indefiniteness can express magnification: the life protected by the rule is not merely one immediate instance, but a far-reaching social good.
Its consequences may include the prospective victim, the person deterred from murder and others protected by a more secure social order. This wide sense is concentrated into one noun, an important feature of ījāz al-qaṣr.
