«وَمِنْهُ التَّقْسِيمُ: وَهُوَ ذِكْرُ مُتَعَدِّدٍ، ثُمَّ إِضَافَةُ مَا لِكُلٍّ إِلَيْهِ عَلَى التَّعْيِينِ»
“Taqsīm mentions several things and then explicitly assigns to each what belongs to it.”
The cited verse contrasts two painful states and then specifies the particular consequence connected with each. The audience is not left to guess the distribution.
This resembles laff wa-nashr in having multiple earlier items and later details, but here the defining emphasis is on explicit determination of which property belongs to which item.
