God has strictly prohibited alcoholic drink and gambling!

Verse 219 of Chapter 2

They ask you (O Muhammad ) concerning alcoholic drink and gambling. Say: "In them is a great sin, and (some) benefits for men, but the sin of them is greater than their benefit.'' And they ask you what they ought to spend. Say: "That which is (spare) beyond your needs.'' Thus Allah makes clear to you His Laws in order that you may give thought.

Verse 43 of Chapter 4

O Believers, do not offer the Prayer while you are intoxicated, for Prayer should be offered only when you know what you are saying. Likewise, do not offer the Prayer if you are "unclean" until you take your bath, except when passing on the way: and if you are sick or on a journey or if any one of you has relieved himself or you have touched women and can find no water, then cleanse yourselves with pure dust by rubbing it on your face and hands; no doubt Allah is Lenient and Forgiving. 

Verses 90-92 of Chapter 5
O Believers, wine, gambling, (ungodly) shrines and divining devices are all abominable works of Satan: therefore refrain from these so that you may attain to true success. Indeed Satan intends to sow enmity and' hatred among you by means of wine and gambling, and to prevent you from the remembrance of Allah and from Salat. Will you not, therefore, abstain from these things? Obey Allah and His Messenger and abstain from these things; but if you disobeyed, note it well that Our Messenger's only responsibility was to convey the Message clearly.
