Musannaf Ibn Abi Shaybah

It is narrated from Hammad, he says that nabidh made from the raisins of Ta’if was brought to Umar. The narrator says: When he tasted it, he wanted to dilute it and said: Surely, the nabidh of the raisins of Ta’if is strong. Then he called for water and poured it into it, then drank it. And he said: If any of you finds nabidh too strong, then add water to it and drink it.
