«وَاللَّهِ مَا بَرَّةٌ بِعُرْسِي / وَلَا لِيَ ابْنٌ بِهِ اكْتَنَيْتُ»
By God, Barra is not my wife, nor do I have a son after whom I took my kunya.
After wa-llāhi, the speaker explicitly negates the supposed wife and son. What earlier appeared to be an affecting family narrative is now recast by the narrator’s own statement.
The oath intensifies the assertion, but the narrative turning point lies in the actual content of the denial. The paired mā ... wa-lā negates two relationships. This is a confession about fabrication, not simply a display of eloquent negation.
Practice: How does the denial change the previous story? It is revealed as an invented family claim.
