Wāw al-ittiṣāl concerns the conjunction as a link in an ongoing construction. Depending on the case, it can connect the unfolding consequence of a scene or give rise to grammatical discussion about how a longer passage is organized.
«إِذَا وَقَعَتِ الْوَاقِعَةُ»
“When the Event occurs.” (al-Wāqiʿah 56:1)
«وَكُنْتُمْ أَزْوَاجًا ثَلَاثَةً»
“And you become three groups.” (al-Wāqiʿah 56:7)
The verses between these expressions describe the onset of the Last Day. The later clause belongs to that developing scene; it should not be treated as an unrelated announcement merely because several verses intervene.
The force of the conjunction emerges from the whole construction, not only the English word “and.”
