Mishkat al-Masabih — Hadith #51391

On the authority of Ibn Abbas, he said: The Messenger of God, may God’s prayers and peace be upon him, used to make water for him at the beginning of the night, and he would drink it when that day came. And the night that comes, and the next day, and the next night, and the next until the afternoon, and if there is anything left, the servant gives it to drink or orders it to be poured out.
