Narrated 'Amr bin Shurahbil [Abu Maisarah]:
from 'Umar bin Al-Khattab, that he said: "O Allah! Make the verdict concerning Khamr sufficiently clear for us!" So (the Ayah) in Al-Baqarah was revealed: They ask you concerning Khamr and gambling. Say: "In them is a great sin (2:219)." So 'Umar was called, and it was recited to him, so he said: "O Allah! Make the verdict concerning Khamr sufficiently clear for us!" So (the Ayah) in An-Nisa was revealed: 'O you who believe! Approach not As-Salat while you are in a drunken state (4:43).' So 'Umar was called and it was recited him, so he said "O Allah! Make the verdict concerning Khamr sufficiently clear for us!" So (the Ayah) in Al-Ma'idah was revealed: Shaitan only wants to excite enmity and hatred between you with Khamr and gambling...' up to His saying: 'So will you not then abstain (5:91).' So 'Umar was called and it was recited to him, so he said: 'We abstained, we abstained.'"
