How sound are the narrations that describe Luqman the Wise as "an Abyssinian slave, thick-lipped, splay-footed, a judge over the Children of Israel," or "a black slave, thick-lipped, cracked-footed," or "black from the Sudanese of Egypt"? And is this description authentically established?

The scholars of Hadith have not authenticated the narrations regarding Luqman being a black slave or describing his features, even though the exegetes have cited them. This is due to the weakness of their chains of transmission. The majority of the Salaf held that he was not a prophet, but rather a righteous wise man.
