Can Male Slave Have Concubines as per Hanabilah?

I have confusion regarding the claim which made by Jonathan AC Brown in his book about that some scholars, held the view that not just free men but even slaves could have concubines though they can only own if there master permits either by giving his own slave girl or slave can buy slave girl. Here is the source. I came across only an explanation of Al Kafi of Ibn Qudamah by Shaykh Ibn Uthymeen but I got confused about whether it was permissible or not. Here is the link to Shaykh's explanation. So, what is the Mutamad opinion among Hanabilah regarding this?
