It has been related on the authority of Imam Ja'far As-Saadiq, peace be upon him: The drinking of wine is the key of all evil, and the addict of wine negates his reasoning, removes his light, destroys his manliness and it encourages him to be bold in committing the unlawful. (It causes) the shedding of blood and committing fornication.

He does not believe while he is intoxicated that he is jumping to his unlawful deeds and he does not rationalize that and that his drinking only increases every evil. He said that it is the mother of filth and the head of every evil. There will come to the drinker of wine an hour wherein his intellect is nullified and he is not aware of his Lord.

He does not abandon disobedience except by committing it nor abandon the forbidden except by fatigue nor abandon a family relation except by breaking it and there is no depravity except that he will commit it. He who drinks a drink of wine, Allah does not accept his prayers for forty days. He who drinks one sip of wine, Allah the Almighty and Majestic, His angels, His Messengers and the believers curse him.

If he drinks until becoming intoxicated from it, the spirit of faith (Imaan) is withdrawn from his body and the feeble-mindedness, filthy, accursed spirit will embark, then, he will abandon the prayer. Issue 928: Intended by wine is every fluid intoxicant. Beer is also counted as one the wines. Drinking even one drop of wine is forbidden, even less than that is also forbidden. Issue 929: Sitting at the table at which wine is being drunk is forbidden.

Eating from the table, when it is man, he is counted as one of them although the food is lawful. Issue 930: When the life of a Muslim is in danger by reason of hunger or thirst, it is obligatory upon all that they give him food and water and save him from death. At that time, it is lawful for him to eat some of the unlawful things when he does not find any other thing besides it.

The Recommended acts of Eating Issue 931: Performing a number of acts is recommended at the time of eating in hope of divine reward, they are: To wash the hands before eating. To wash the hands after eating and dry them with a towel. That the host begins eating before all and finish eating after all. To say: Bismillah (In the name of Allah) before eating and after finishing eating to say: Al-Hamdu Li-llah (The Praise is for Allah).

When there are a number of types of food on the table, say Bismillah at the time eating each type of food.
