«حَتَّى تَنْكِحَ زَوْجًا غَيْرَهُ»
Until she marries a husband other than him.
In the discussion of remarriage after an irrevocable triple divorce, the verse mentions marriage to another husband. The related report introduces the question of consummation. Classical jurists give different accounts of how that condition is established and how reports relate to the verse.
The pedagogical point is the evidence required for an added qualification, not practical instructions for arranging marriage or divorce.
