What is the ruling on a Muslim helping a non-Muslim with money to buy alcohol, or transporting him to commit evils and grave sins?

It is not permissible to help a disbeliever or a Muslim purchase alcohol or commit any other sins and transgressions, for doing so is sinful and leads to loss. Allah has forbidden this, saying: ﴿And cooperate in righteousness and piety, but do not cooperate in sin and aggression.﴾ Furthermore, the Messenger of Allah, peace and blessings be upon him, cursed ten categories of people related to alcohol, among them the purchaser and the one for whom it is purchased. Thus, whoever drinks alcohol or assists in its consumption deserves to be cursed.
