Ibrahim reported: I said to Aswad if he had asked the Mother of the Believers (in which utensils) he (the Holy Prophet) disapproved the preparation of Nabidh. He (Aswad) said: Yes. I said: Mother of the Believers, inform me about the utensils in which) Allah’s Apostle forbade to prepare Nabidh. She (Hadrat ‘Aisha) said: He forbade us, the members of his family, to prepare Nabidh in gourd, or varnished jar. I said to him: Do you remember green pitcher, and pitcher? He said: I narrated to you what I have heard; should I narrate to you which I did not hear?
