Imam al-Sha'bi reports that his paternal uncle said: For a year I kept visiting Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), and I never found him keeping (voluntary) fasts in any month other than Ramadan. He used to drink strong nabidh prepared in green jars. In the chain of this narration is a narrator, Ismah bin Sulayman, and a narrator who is the paternal uncle of Imam al-Sha'bi, and I have not found anyone who has given biographical notices of the two of them.
