Abu Dawood says: I have heard this detail of the ages of camels from Riyashi, Abu Hatim, and others, and have obtained it from the book of Nadr bin Mushmil and Abu Ubaid, and some things have been mentioned by only one of them. These people say: The baby camel (when it is born) is called «حواءر» . When it is weaned, it is called «فصیل» . When it completes one year and enters the second year, until the completion of the second year, it is called «بنت مخاض» . When it enters the third year, it is called «بنت لبون» . When it completes three years, until the completion of four years, it is called «حِق» or «حقہ» , because it becomes suitable for riding and mating, and the she-camel (female) becomes pregnant at this age, but the male does not become mature until it reaches double the age (six years). «حقہ» is also called «طروقۃ الفحل» , because the male mounts it. When it enters the fifth year, until the completion of five years, it is called «جذعہ» . When it enters the sixth year and sheds its front teeth, until the completion of six years, it is «ثنی» . When it enters the seventh year, until the completion of seven years, the male is called «رباعی» and the female is called «رباعیہ» . When it enters the eighth year and sheds the sixth tooth, until the completion of eight years, it is called «سدیس» or «سدس» . When it enters the ninth year, until the beginning of the tenth year, it is called «بازل» , because its canines appear. It is said «بزل نابه» , meaning its teeth have appeared. And when it enters the tenth year, it is «مخلف» ; after that, it has no specific name, but it is said: one-year-old «بازل» , two-year-old «بازل» , one-year-old «مخلف» , two-year-old «مخلف» , and three-year-old «مخلف» ; this sequence continues up to five years. «خلفہ» is called a pregnant she-camel. Abu Hatim said: «جذوعہ» is the name of a period, not of a specific tooth; the change of teeth occurs at the rising of the Suhail star. Abu Dawood says: Riyashi recited poetry to us (the meaning of which is): When Suhail (the star) rises at the end of the night, «ابن لبون» becomes «حِق» and «حِق» becomes «جذع» , no tooth remains except «ہبع» . «ہبع» : It is the baby that is not born at the time of the rising of Suhail, but is born at some other time; its age is not counted from Suhail.
