لَا وَالَّذِي هُوَ عَالِمٌ أَنَّ النَّوَى صَبِرٌ وَأَنَّ أَبَا الْحُسَيْنِ كَرَمُ
No—by Him who knows that parting is as bitter as ṣabir and that Abū al-Ḥusayn embodies generosity.
Here ṣabir does not mean patience: it denotes an intensely bitter plant-derived substance. The first predication likens separation to bitterness; the second identifies Abū al-Ḥusayn with generosity.
At first glance the bitterness of parting and the generosity of a particular man belong to different semantic fields. The example therefore tests whether the listener can find a defensible conceptual or imaginative link—such as the contrast between bitterness and the sweetness associated with generosity—instead of assuming that the mere presence of wāw is sufficient.
