Amr bin Dinar عمرو بن دينار الأثرم الجمحي · The Book on Business

That the Messenger of Allah (ﷺ) said: "When one of you (women) has a Mukatab ho has with him what will fulfill (the Kitabah) then observe Hijab from him." This Hadith is Hasan Sahih. And the meaning of this Hadith according to the people of knowledge is that of caution. They say that the Mukatab is not freed, even if he has the amount to pay, until he pays it.

From Abu Hurairah who said: "The price of a dog was prohibited, except for the hunting dog." This Hadith is not correct from this route. Abu Al-Muhazzim's name is Yazid bin Sufyan, and Shu'bah bin Al-Hajjaj criticized him and graded him weak. Similar to this has been reported from Jabir, from the Prophet (ﷺ), but its chain is also not correct.
