The compiler of this book, may Allah سبحانه وتعالى have mercy on him, said: I heard a man from among those knowledgeable in language in Kufa say that the term "Qabba" refers to a horse with a slender belly. It is said "faras aaqab" (a horse that is lean) and "Qabba" refers to both male and female horses. However, for a female horse, it is exclusively called "Qabba" and nothing else. The poet Dhul-Rummah said: It stood erect around him one day, observing him, Tall wild donkeys with slender bellies. The term " Ṣuhr" is the plural of "Aṣhar", referring to an animal whose color tends towards redness, which is commonly found in wild donkeys. "Samahij" refers to tall animals, the singular being "Samhaj", and "Qabab" means slenderness.
