In the name of Allah, the Most Gracious, the Most Merciful
Al-Baqarah
(2:219) They ask you about drinking and gambling. Tell them: “There is great sin in both, although they may have some benefit for men; but the sin is greater than the benefit.” They ask you what they should spend; tell them: “Whatever you can.” Thus Allah makes His revelations clear to you, so that you may reflect upon
(2:220) this world and the hereafter. They ask you about orphans. Tell them: “It is best to deal with them justly; you may become co-partners with them, after all they are your brethren; Allah knows who means harm and also who means their welfare. If Allah had wanted He could be hard on you in this matter, surely Allah is Mighty, Wise.
An-Nisa
(4:43) O believers! Do not offer your prayer (Salah) when you are drunk until you know what you are saying; nor after seminal emission, except when you are traveling, unless you wash your whole body. If you are sick, or on a journey, or one of you has used the toilet, or has had contact with women (sexual relation with wives) and can find no water, then make Tayammum: take some clean earth and rub your faces and hands with it. Allah is Lenient, Forgiving.
Al-Ma’idah
(5:90) O you who have believed, indeed, intoxicants, gambling, [sacrificing on] stone alters [to other than Allah], and divining arrows are but defilement from the work of Satan, so avoid it that you may be successful.
(5:91) Satan only wants to cause between you animosity and hatred through intoxicants and gambling and to avert you from the remembrance of Allah and from prayer. So will you not desist?
