Shaykh of shias Shahid ath-Thani in his “Masalik al-Afham” (7/52) said:

 وروى الكليني أخبارا (٤) كثيرة بطرق صحيحة عن الصادق عليه السلام أن المراد بقوله تعالى: (أو ما ملكت أيمانهن) شامل للمملوك مطلقا.

And Kulayni narrated many reports via sound chains from as-Sadiq (alaihi salam) that meaning of the words of Taala: (Noor 31) or those whom their right hands possess- refer in general to slaves.

As you can see in the footnote muhaqiq said:

لم نجد في الكافي بهذا المضمون إلا حديثا واحدا، راجع الكافي ٥: ٥٣١ ح ٢.

We didn’t find in al-Kafi (reports) with such meaning except one hadith, see al-Kafi (5/531/h2)

Other shia scholar, Abul Qasim al-Khui in his “Kitab an-Nikah” (1/93):

After quoting words of Shahid ath-Thani, he said:

لم يرد في الكافي ما يمكن جعله دليلا لكلام الشهيد (قده) غير صحيحة (2) معاوية بن عمار

It is not present in al-Kafi what could be used as proofs for words of Shahid except sahih of Muawiyah ibn Ammar….

So very logical in our view is question for all shias, where from Kafi gone MANY REPORTS in that meaning which mentioned Shahid?
