Hadith 37:70
Ali bin Mushir narrated to us, from al-Mukhtar bin Fulful, from Anas bin Malik, who said: The Messenger of Allah (may Allah bless him and grant him peace) said to me: "Al-Kawthar is a river my Lord promised me, upon it is much good. It is my cistern (Hawd) which my nation will come to on the Day of Resurrection. Its vessels are the number of the stars. Then a servant from among them will be snatched away, so I will say: 'O Lord, he is from my nation.' He will say: 'You do not know what he introduced after you.'"
حدثنا على بن مسهر عن المختار بن فلفل عن أنس بن مالك قال قال لي رسول الله صلى الله عليه وسلم الكوثر نهر وعدني ربي عليه خير كثير هو حوضي ترد عليه أمتي يوم القيامة آنيته عدد النجوم فيختلج العبد منهم فأقول رب إنه من أمتي فيقول لا تدري ما أحدث بعدك
