When the prohibition of wine (was yet to be) declared, Umar said: O Allah, give us a satisfactory explanation about wine. So the following verse of Surat al-Baqarah revealed; "They ask thee concerning wine and gambling. Say: In them is great sin...." Umar was then called and it was recited to him. He said: O Allah, give us a satisfactory explanation about wine. Then the following verse of Surat an-Nisa' was revealed: "O ye who believe! approach not prayers with a mind befogged...." Thereafter the herald of the Messenger of Allah ﷺ would call when the (congregational) prayer was performed: Beware, one who is drunk should not come to prayer. Umar was again called and it was recited to him). He said: O Allah, give us a satisfactory explanation about wine. This verse was revealed: "Will ye not then abstain?" Umar said: We abstained.
