Thawban reported,

The Prophet of Allah ﷺ said, "I will be at the edge of my Pool driving people away to make room for the people of Yemen. I will strike with my staff until the water flows abundantly over them."He was asked about its breadth, and he replied, "From where I stand to Amman."He was asked about its drink, and he replied, "Whiter than milk and sweeter than honey. Two spouts pour into it abundantly, supplying it from Paradise, one of gold and the other of silver."

Sahih

عن ثوبان

أن نبي الله ﷺ قال: إني لبعقر حوضي أذود الناس لأهل اليمن أضرب بعصاي حتى يرفض عليهم. فسئل عن عرضه فقال: من مقامي إلى عمان. وسئل عن شرابه فقال: أشد بياضا من اللبن، وأحلى من العسل يغت فيه ميزابان يمدانه من الجنة، أحدهما من ذهب، والآخر من ورق.
