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.
