It was
narrated from Abu Sa’eed Al-Khudri that the Prophet (ﷺ)
said:
“I
have a Cistern, (as large as the distance) between the Ka’bah
and
Baitul-Maqdis (Jerusalem). (It is) whiter than milk, and its
vessels
are the number of the stars. I will be the Prophet with the
most
followers on the Day of Resurrection.”
