Surah Al-Baqarah 2:219 البقرة

O Prophet, your Companions ask you about wine (which refers to anything that impairs the mind or intoxicates it), specifically concerning the legality of its drinking, selling, and purchasing. They also ask you about gambling (which refers to wealth taken in a competition between two people in which both contribute to the winning total). In response to them, say: They both have many spiritual and worldly harms, such as loss of intellect and wealth and breeding hatred and enmity. On the other hand, there are a few benefits, such as a financial reward for the winner of a bet. However, the harm and sin resulting from them outweigh the benefits, so a logical person should avoid such actions. This statement of Allah lays the foundation for the prohibition of wine. They also ask you, O Prophet, how much they should spend on charity. Say in reply to them: Spend whatever is easy and in excess of your needs. With such clear explanations, Allah describes the sacred law to you so that you may reflect. Initially, this was the law regarding charity, but later, Allah established the obligation of Zakat, which requires paying a set amount on certain possessions if one has owned such possessions for a particular period of time.
