He was asked: What is tinat al-khabal, Messenger of Allah? He replied: Discharge of wounds, flowing from the inhabitants of Hell. If anyone serves it to a minor who does not distinguish between the lawful and the unlawful, it is binding on Allah that He will give him to drink the discharge of wounds, flowing from the inhabitants of Hell.
