Muwatta Imam Malik (Riwayat Ibn al-Qasim)

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that (once) the Messenger of Allah (peace and blessings be upon him) went towards the graveyard and said: "Peace be upon you, O abode of the believers! And, God willing, we will join you. I wished that I could see my brothers!" The Companions said: O Messenger of Allah! Are we not your brothers? He (peace and blessings be upon him) said: "Rather, you are my Companions, and my brothers are those who have not yet come (into the world), and I will be present at the (Kawthar) pond before them." The Companions asked: O Messenger of Allah! How will you recognize those members of your Ummah who will come after you (in the world)? He (peace and blessings be upon him) said: "What do you think, if a man has horses among which some have white faces and white feet, and they are among black horses, will he not recognize his own horses?" The people replied: Surely, he will recognize them. He (peace and blessings be upon him) said: "These people (my Ummah) will come on the Day of Resurrection in such a state that their faces and hands and feet will be shining white, and I will be present at the pond before them. Then some people will be driven away from my pond just as a lost camel is driven away. Then I will call out to them (three times): Come here, come here, come here! Then it will be said (to me): They changed (your Sunnah and the religion of Islam) after you. So I will say: Be gone, be gone, be gone."
