It is narrated from Hazrat Qais bin Abi Hazim, he says that Utbah bin Farqad told me that I presented myself before Hazrat Umar, and he called for a large bowl in which there was nabidh, which was close to becoming vinegar. Hazrat Umar said, "Drink it." I took the bowl and drank it, but it did not go down my throat easily. Then Hazrat Umar took the bowl and drank it, and then said, "O Utbah! We drink this strong type of nabidh so that by means of it we may digest the camel meat in our stomachs, so that it does not cause us harm."
