«وَهُوَ الَّذِي وَشَى الشِّعْرَ الْمَنْسُوجَ»
He is the one who embroidered the woven poetry.
Washā means to decorate or embroider, while mansūj means woven. Together they extend the textile metaphor: the poet first weaves the composition, then ornaments it. The answer corroborates the elder’s literary skill as well as his origin.
