1. [1/214] al-Kafi: A number of our companions from Ahmad b. Muhammad from Muhammad b. Ismail from Ibrahim b. Abi al-Ballad from Muawiya b. Ammar who said:

we were about thirty men in the presence of Abi Abdillah عليه السلام when my father entered in to see him. Abu Abdillah عليه السلام welcomed him, made him sit by his side and turned to him [to talk] for a long time, then Abu Abdillah عليه السلام said: Abi Muawiya has a private request so if you could all leave us, we all stood but my father said to me: return O Muawiya, so I returned. Abu Abdillah عليه السلام said: this one is your son? He [my father] said: yes, he claims that the people of Madina do something which is not permitted for them, he [the Imam] said: what is that? I [Muawiya] said: a Qurashi and a Hashimi woman mounts [a camel] by putting her hand on the head of a black slave and while her forearm is on his neck [for support]. Abu Abdillah عليه السلام said: O son – do you read the Qur’an? I said: yes, he said: read this verse: “there is no blame upon women [to expose themselves to] their fathers or their sons … or those their right hands possess [slaves]” (33:55), then he said: O son, there is no harm if the slave sees the hair and the shin [of a non-Mahram woman].
