“(Narrated) Ali bin Ibrahim, from Haroon bin Muslim, from Mas’adah bin Ziyad, from Abu Abdullah [as] said: Amirul-Mu’mineen (Ali) [as] said:
Beware of marrying the Negros (zunj) for they are a distorted creation.”
al-Kafi (fil Furoo’): Book of Nikah, Chapter: Whom (the Imam) Disliked for Marriage Amongst the Kurdish, Negros and Others, vol. 5, p. 352, Narration 1.
Comment: See, even a special chapter has been written to show the gravity of the situation.
(Narrated) Ali bin Ibrahim, from Ismael bin Muhammad al-Makki, from Ali bin al-Husain, from ‘Amr bin Othman, from al-Husain bin Khalid, from whom he mentioned from Abu Ar-Rabi’ al-Shami said: Abu Abdullah [as] said to me:
Do not buy anyone who is a negro, but if you must, then (buy) the Nubians, for they are amongst those whom Allah the Exalted said about them: 5.14 From those too, who call themselves Christians, We did take a covenant, but they forgot a good part of the Message that was sent them . Surely, a time will come when they will remember that portion, and when the Qa’im (Mahdi) arise, a group of them will come to his support, but never marry anyone of the Kurdish (people) for they are part of the Jinn (demons) whom the screen was lifted from them”
Ibid, narration 2
Comments: by “whom the screen was lifted from them” he meant, the screen or divider which Allah has created between us human and Jinn, where we are unable to see them but they can see us. The Kurds, according to this narration, are a type of demons which we are enabled to see.
” (Narrated) Several of our fellows from Sahl bin Ziyad, from Musa bin Ja’far, from ‘Amr bin Sa’eed, from Muhammad bin Abdillah al-Hashimi, from Ahmad bin Yousuf, from Ali bin Dawood al-Haddaad, from Abu Abdullah [as] said:
Marry not from the Negros nor the Khazar, for they have uteruses indicate they are unfaithful. He [as] further said: India, Sind and Qind not a single one of them is smart, meaning Qandaharis
Ibid, Narration 3.
Comments: Khazar is the area around the black sea, and Qandahar is in Afghanistan, where the Pashtuns live.
