وَامْرَأَتُهُ حَمَّالَةَ الْحَطَبِ
And his wife, the carrier of firewood. (111:4)
Imraʾatuhu is nominative. Recognized parses include treating it as a new subject or coordinating it with the subject of yaṣlā. The wāw connects the introduction of this second person to the preceding account, rather than serving as a sound ornament.
Good analysis first fixes the word’s inflection and possible syntactic connection, then asks what additional rhetorical point the named companion contributes to the passage.
