Allah's Messenger (ﷺ) said, "The width of my Lake-Fount is equal to the distance between Aila (a town in Sham) and Sana' (the capital of Yemen) and it has as many (numerous) jugs as the number of stars of the sky."
Sahih al-Bukhari Book 81, Hadith 168
← Previous Hadith The Prophet (ﷺ) said, "My Lake-Fount is (so large that it takes) a month's journey to cross it. Its water is whiter than milk, and its smell is nicer than musk (a kind of Perfume), and its drinking cups are (as numerous) as the (number of) stars of the sky; and whoever drinks from it, will never be thirsty."

Sahih al-Bukhari Book 81, Hadith 167 Next Hadith → The Prophet (ﷺ) said: "While I was walking in Paradise (on the night of Mi'raj), I saw a river, on the two banks of which there were tents made of hollow pearls. I asked, "What is this, O Gabriel?' He said, 'That is the Kauthar which Your Lord has given to you.' Behold! Its scent or its mud was sharp smelling musk!" (The sub-narrator, Hudba is in doubt as to the correct expression. )
