The Women - 4:43
Believers! Do not stand in prayer while intoxicated until you know what you say, and do not pray until you have washed after sexual intercourse, except for those who are travelers. And if you are sick or a pilgrim, or if one of you has come from the toilet, or if you have had sexual intercourse with women and have not found water, then do tayammum by touching a clean and dry earth and rubbing it on your face and hands. Allah Forgives, Forgives.
About intoxicants:
The Table Spread/5:90
Believers, intoxicants, gambling, sacred stones and shrines, and games of chance are filth from Satan. Avoid them so that you may be saved.
The Table Spread/5:91
Satan wishes to put enmity and hatred between you by intoxicants and gambling and to keep you from the remembrance of Allah and from prayer. Are you not giving up now?
The Cow/2:219
"They ask you about intoxicants and gambling: Say: "There is a great sin in both of them and benefits for mankind, but their sin is greater than their benefit."They also ask you what they should give in charity: Say, "The surplus."This is how Allah explains His verses so that you may reflect"
