The Messenger of Allah ﷺ went out to the graveyard and said, "Peace be upon you, abode of a believing people. We, Allah willing, will be joining you. How I wish I could see our brothers."The companions asked, "Messenger of Allah, are we not your brothers?"He replied, "You are my companions. Our brothers are those who have not yet come. And I will precede them to the Pool."They asked, "Messenger of Allah, how will you recognize those of your community who come after you?"He said, "Tell me, if a man had horses with white blazes on their foreheads and white markings on their legs among jet-black horses, would he not recognize his own horses?"They replied, "Of course, Messenger of Allah."He said, "They will come on the Day of Resurrection with bright faces and bright limbs from the traces of ablution, and I will precede them to the Pool. Some men will be driven away from my Pool just as a stray camel is driven away. I will call out to them, 'Come here! Come here! Come here!' But it will be said, 'They changed things after you.' So I will say, 'Away with them, away with them, away with them.'"
أن رسول الله ﷺ خرج إلى المقبرة فقال: السلام عليكم دار قوم مؤمنين وإنا إن شاء الله بكم لاحقون، وددت أني قد رأيت إخواننا، فقالوا: يا رسول الله! ألسنا بإخوانك؟ قال: بل أنتم أصحابي، وإخواننا الذين لم يأتوا بعد، وأنا فرطهم على الحوض، فقالوا: يا رسول الله! كيف تعرف من يأتي بعدك من أمتك؟ قال: أرأيت لو كان لرجل خيل غر محجلة في خيل دهم بهم، إلا يعرف خيله؟ قالوا: بلي يا رسول الله! قال: فإنهم يأتون يوم القيامة غرا محجلين من الوضوء، وأنا فرطهم على الحوض، فليدادن رجال عن حوضي، كما يذاد البعير الضال، أناديهم: ألا هلم! ألا هلم! ألا هلم! فيقال: إنهم قد بدلوا بعدك، فأقول: فسحقا فسحقا فسحقا.
Malik narrated it in Purification (28) from Ala bin Abdul-Rahman, from his father, from Abu Hurairah, and he related the hadith, and this is his wording. Muslim narrated it in Purification (249) through Malik and others, from Ala bin Abdul-Rahman, with the same wording.
