Chapter 26: The Book on Drinks
Narrated 'Umar bin Al-Khattab: "Indeed Khamr comes from wheat."[After mentioning this, he said: ] and this is more correct than the narration of Ibrahim bin Muhajir (no. 1872). 'Ali bin Al-Madini said: "Yahya bin Sa' eed said: 'Ibrahim bin Al-Muhajir is not strong [in Hadith].'" And it has also been reported through other rotes from Ash-Sha' bi, from An-Nu' man bin Bashir.
