[He said:] There is something similar to this topic from Salamah bin Al-Muhabbaq. [Abu 'Eisa said:] The chain of An-Nu'man contains some confusion (Idtirab). He said: I heard Muhammad bin Isma'il saying: "Qatadah also did not hear this Hadith from Habib bin Salim, he only reported it from Khalid bin 'Urfutah." [Abu 'Eisa said:] The people of knowledge differ over the case of a man who has relations with his wife's slave girl. It has been reported from more than one of the Companions of Prophet (saws) - among them 'Ali and Ibn 'Umar - that he is to be stoned. Ibn Mas'ud said: "The legal punishment is not required for him, but he may be punished." Ahmad and Ishaq followed what was reported from An-Nu'man bin Bashir from Prophet (saws).
