Sahih Muslim 5990

Thauban reported Allah's Apostle (ﷺ) as saying:I would be pushing back from my Cistern the crowd of people. I would strike away from it (the Cistern) with my staff the people of Yemen until the water (of the Haud) would spout forth upon them. He was asked about its breadth. He said: From this place of mine to 'Amman, and he was asked about the drink and he said: It is whiter than milk and sweeter than honey.

This hadith has been narrated on the authority of Hisham with the same chain of transmitters and the words are:" I would be on the Day of Resurrection near the bank of the Cistern
