It is narrated from Hazrat Abu Wa'il, he says that a man from the tribe had a complaint of the stomach. It was said to this man that there are worms in your stomach. And the physicians prescribed unripe date juice for him. This man sent someone to Hazrat Abdullah to ask about this issue. So Hazrat Abdullah replied: Surely, Allah Almighty has not placed your cure in anything that He has made unlawful for you.
