The passage develops three distinct linguistic choices, each affecting the report in a different way.
Coordination (ʿaṭf) controls whether another participant shares, is excluded from, corrects, or remains an alternative in a judgment. The particles wāw, fāʾ, thumma, lā, bal and aw have distinct contributions.
Preposing (taqdīm) can orient attention toward a person rather than an event, sometimes producing contrast or strengthening a judgment. Word order alone does not prove exclusivity in every sentence.
Negation with universal expressions fixes scope: denying a proposition of everyone is not the same as denying it of every individual. The contrast between “كل ... لم” and “لم ... كل” has logical consequences.
The next lesson continues the remaining subject constructions and their context-dependent rhetorical purposes.
