It was narrated from Abu Hurairah that the Prophet (ﷺ) came to a graveyard and greeted (its occupants) with Salam, then he said:
“Peace be upon you, abode of believing people. We will join you soon, if Allah wills.” Then he said: “Would that we could see our brothers.” They said: “O Messenger of Allah, are we not your brothers?” He said: “You are my Companions. My brothers are those who will come after me. I will reach the Cistern ahead of you.” They said: “O Messenger of Allah, how will you recognize those of your nation who have not yet come?” He said: “If a man has a horse with a blaze on its forehead and white feet, don’t you think that he will recognize it among horses that are deep black in color?” They said: “Of course.” He said: “On the Day of Resurrection they will come with radiant faces, hands, and feet, because of the traces of ablution.” He said: “I will reach the Cistern ahead of you.” Then he said: “Men will be driven away from my Cistern just as stray camels are driven away. And I will call to them: ‘Come here!’ But it will be said: ‘They changed after you were gone, and they kept turning on their heels.’ So I will say: “Be off with you!”
