Sahl bin Saad reported,

I heard the Prophet ﷺ say, "I will arrive at the Pool before you. Whoever comes to it will drink from it, and whoever drinks from it will never thirst again. People will come to me whom I recognize and who recognize me, then a barrier will be placed between me and them."Abu Hazim said, Numan bin Abu Ayyash heard me narrating this and asked, "Is this how you heard it from Sahl?"I replied, "Yes."He said, "And I bear witness that I heard Abu Saeed Khudri narrating it with an addition. He said, 'I will say, They are from me. It will be said, You do not know what they introduced after you. So I will say, Away with them, away with those who changed after me.'"

Sahih

عن سهل بن سعد، يقول

سمعت النبي ﷺ يقول: أنا فرطكم على الحوض، من ورد شرب منه، ومن شرب منه لم يظمأ بعده أبدا، ليرد علي أقوام أعرفهم ويعرفوني، ثم يحال بيني وبينهم. قال أبو حازم: فسمعني النعمان بن أبي عياش، وأنا أحدثهم هذا. فقال: هكذا سمعت سهلا؟ فقلت: نعم، قال: وأنا أشهد على أبي سعيد الخدري لسمعته يزيد فيه، قال: إنهم مني، فيقال: إنك لا تدري ما بدلوا بعدك، فأقول: سحقا سحقا لمن بدل بعدي.
