Hadith 15:119
Abu Bakr narrated to us, he said: Abd al-Rahim ibn Sulayman narrated to us, from Abu Ya'fur Abd al-Rahman ibn Ubayd al-Amiri, from Ayman Abu Thabit, who said: I was sitting with Ibn Abbas when a man came to him and asked him about juice (al-asir). He said: "Drink it as long as it is fresh."
