When it tenses, it is stronger for lifting the leg. When it relaxes, the leg relaxes. When it tenses before the woman, it is a grip on the hock. When its leg relaxes before it, it is a loosening for the woman. The poet said: (He who grips the hock) "And his hooves are hard, and what remains of the pain, as if the place of the rump was on him."

His saying "and his hooves are hard" means his hooves. What remains of the pain, meaning what is left. The horse's hooves. It splits if it is tired from walking or from pain. Pain is when the horse feels pain in its hoof, complaining of it without any crack or anything else. The hoof is what the earth rubs and eats away at. The impact is the striking of stones on its hooves when it walks.

This is the saying of Al-Asma'i. Others said that "al-hafa" and "al-radif" mean the hindquarters of something. And "al-radif" is what you ride, and "radaytu" means I rode. "Al-za'al" is the ostrich, and it is hamzated. "Al-hamz" is like the "qafah" and "al-qutah" is the seat of the rump, and its prominent parts are stretched out, so it is compared to it. The cloud, and its singular is "ghaythah." When it is raining, it is called "ghayth" because they are from the rain. "Al-wasmi" is the first rain of autumn, and it is called "wasmi" because it marks the land, and the land is marked by it. "Al-ra'id" is one who scouts for pasture, and "al-khala'" is what is in the wilderness. So the poet means that he will be the first to reach this pasture that people are afraid of due to the severity of the drought. His saying "and he is not afraid" can mean that his scout is in a place of wilderness. It can also mean that it is from the "qutham" of a man in the wilderness. When it is in a place of wilderness, it is called "qutham." And "qutham" is a ruined place. He said, and if it is from it, like the "qutham" of a man in a ruined place, if it is.
