"My Cistern is wider than the distance between Ailah and "Aden. By the One in Whose Hand is my soul, its vessels are more numerous than the number of stars, and it is whiter than milk and sweeter than honey. By the One in Whose Hand is my soul, I will drive men away from it as a man drives strange camels away from his cistern." It was said: "O Messenger of Allah, will you recognize us?" He said: "Yes, you will come to me with radiant faces, hands and feet, because of the traces of ablution, and this is not for anyone but you."
