Raisins used to be soaked for the Messenger of Allah (may Allah’s peace and blessings be upon him) in a water skin, and he would drink it that day, the next day, and the following day. In the evening of the third day, he would drink it and give some to others. If anything was left, he would spill it

Explanation of the hadith

In this Hadīth, Ibn ‘Abbās (may Allah be pleased with him) reports that Nabīdh would be prepared for the Prophet (may Allah's peace and blessings be upon him) by leaving raisins or dates in water in a container so that it may become sweet and have a taste. The Prophet (may Allah’s peace and blessing be upon him) would drink the Nabīdh for three days. On the third night, if the taste of Nabīdh had not changed, the Prophet (may Allah's peace and blessings be upon him) would drink it himself, and he would serve it to others so that it would be used up and nothing from it would remain for the fourth day. If something remained from the liquid, he would spill it because it could ferment on the fourth day and the Nabīdh could turn into alcohol.
