«فَسَقَى الْغَضَا وَالسَّاكِنِيهِ وَإِنْ هُمْ شَبُّوهُ بَيْنَ جَوَانِحِي وَضُلُوعِي»
“May the ghaḍā trees and those dwelling there be watered, though they have kindled it between my ribs.”
Al-ghaḍā can denote the tree and, by association, the fire made from its wood. The earlier phrase concerns the tree or its place; shabbūhu turns the pronoun toward the sense of fire.
In istikhdām the reader must identify the two connected referents. A pronoun by itself is not enough to constitute the figure.
