When the prohibition of Khamr was revealed, 'Umar said: "O Allah, give us a clear ruling on Khamr," and the Verse in Al-Baqarah was revealed. 'Umar was called and it was recited to him. Then 'Umar said: "O Allah, give us a clear ruling on Khamr," and the Verse in An-Nisa' was revealed: "O you who believe! Approach not As-Salah (the prayer) when you are in a drunken state". And when the Iqamah for prayer was said, the caller of the Messenger of Allah [SAW] would cry out: "O you who believe! Approach not As-Salah (the prayer) when you are in a drunken state." 'Umar was called and this was recited to him. Then he said: "O Allah, give us a clear ruling on Khamr." Then the Verse in Surat Al-Ma'idah was revealed, and 'Umar was called, and it was recited to him. When he reached the words, "So, will you not then abstain?," 'Umar said: "We have abstained, we have abstained."
