Abu Hurairah reported,

The Messenger of Allah ﷺ went out to the cemetery and said, "Peace be upon you, dwelling of a believing people. Allah willing, we shall join 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. My 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 nation who come after you?"He answered, "Tell me, if a man had horses with white blazes on their foreheads and white markings on their legs among horses that were entirely jet black, would he not recognize his own horses?"They said, "Of course."He said, "On the Day of Resurrection they will come with bright marks on their faces and limbs from the traces of ablution, and I will precede them to the Pool."

عن أبي هريرة

أن رسول الله ﷺ خرج إلى المقبرة فقال السلام عليكم دار قوم مؤمنين وإنا إن شاء الله بكم لاحقون وددت أني قد رأيت إخواننا قالوا يا رسول الله ألسنا إخوانك قال بل أنتم أصحابي وإخواني الذين لم يأتوا بعد وأنا فرطهم على الحوض قالوا يا رسول الله كيف تعرف من يأتي بعدك من أمتك قال أرأيت لو كان لرجل خيل غر محجلة في خيل بهم دهم ألا يعرف خيله قالوا بلى قال فإنهم يأتون يوم القيامة غرا محجلين من الوضوء وأنا فرطهم على الحوض
