The Prophet (may Allah's peace and blessings be upon him) reported that he will have a Cistern on the Day of Judgment whose length takes a month's journey to cross, and so does its breadth; its water is whiter than milk; its smell is more pleasant than the smell of musk; and its drinking cups are as numerous as the stars of the sky. Whoever drinks from that Cistern using these cups will never become thirsty.
