«إِذَا مَا سَابَقَتْهَا الرِّيحُ فَرَّتْ»
When the wind races against the mare, she rushes ahead,
«وَأَلْقَتْ فِي يَدِ الرِّيحِ التُّرَابَا»
and throws dust before the wind.
The verse presents the horse's speed in an extreme image. In the treatment of tabligh, the example conveys an emphatic impression of swiftness rather than a measured numerical claim.
In the Arabic construction, the subject of sabaqatha is “al-rih” (the wind), and the attached pronoun refers to the mare. The subject understood with “alqat” is the mare.
