Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Every intoxicant is wine (khamr), and every intoxicant is unlawful. Whoever drinks an intoxicant, his prayer is not accepted for forty days; if he repents, Allah accepts his repentance. If he drinks a fourth time, it is a right upon Allah that He will give him the pus of the people of Hell to drink. Likewise, whoever gives wine to a small child who does not know the lawful from the unlawful, Allah will also give him the pus of the people of Hell to drink."
