Peace be upon you, the abode of the believers

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, came to the graveyard and he said, “Peace be upon you, the abode of the believers and we will join you, if Allah wills. I love to see my brothers.” They said, “Are we not your brothers, O Messenger of Allah?” He said, “You are my companions, and our brothers are those who have not yet come into the world.” They said, “O Messenger of Allah, how will you recognize the people of your nation who have not yet been born?” He said, “Suppose a man had horses with white blazes on their foreheads and legs among horses which were all dark, would he not recognize his own horses?” They said, “Of course.” He said, “They will come with bright faces and arms and legs due to their ablution, and I will arrive at the fountain ahead of them. Some people will be driven away from my fountain as a stray camel is driven away. I will say: Come! Come! But it will be said to me: These people changed themselves after you. So I will say: Be off! Be off!”
