So in the M, O, and L, and in some copies of the K; in other copies of the K, مُطْفِئُ.
The stones meant are the رَضْف, [or heated stones].
he slaughtered for them a lean sheep or goat, which put out the fire and did not become thoroughly cooked—حَدَسَ لَهُمْ بِمُطْفِئَةِ الرَّضْفِ
In the M and L it is said to signify a lean sheep or goat; the Arabs, as Lh relates, used to say:
So the M and L, and the K in art. حدس; or a fat sheep or goat, which quenched the رَضْف by its fat. [See also دَمَغَ.]
1.2
Also a serpent whose poison, as it passes by the رَضْف, extinguishes their fire.
In a verse of El-Kumeyt the former word is altered to مُطَفِّئَة, for the sake of the metre.
1.3figurative · مجاز
