2. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid, from Yahya ibn Ibrahim ibn abu al-Balad, from his father from his grandfather who has said the following: “I once complained before abu Ja‘far , about stomach trouble and he (the Imam) said, ‘What prevents you from drinking cow milk, have you ever drank it before?’ I replied, ‘Yes, many times.’ He (the Imam) asked, ‘How did you find it?’ I replied, ‘It tans the stomach, covers the kidneys with fat and increases one’s appetite for food.’ He (the Imam) then said, ‘Had it been the right time, you and I could have gone to Yanba’ so we could drink milk.’”

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ahmad ibn Muhammad from ibn abu Nasr from Aban ‘Uthman from Zurarah who has said the following: “One of the two Imam, (abu Ja‘far or abu ‘Abd Allah), ‘Alayhim al-Salam, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘You must drink cow milk; it mixes with every tree.’”
