"I was with Ibn 'Abbas when a man came to him and asked him about juice. He said: 'Drink that which is fresh.' He said: 'I cooked a drink on the fire and I am not sure about it.' He said: 'Did you drink it before you cooked it?' He said: 'No.' He said: 'Fire does not make permissible something that is forbidden.'" (Sahih Mawquf)
