Diriwayatkan daripada 'Uqbah Ibn 'Amir (semoga Allah meridhainya): Pada suatu hari Nabi ﷺ keluar lalu menunaikan solat jenazah ke atas para syuhada Uhud, kemudian Baginda naik ke atas mimbar dan bersabda: "Aku akan mendahului kamu sebagai orang yang terdahulu, dan aku akan menjadi saksi ke atas kamu. Demi Allah! Sesungguhnya aku melihat Kautsar (kolam/telaga) ku sekarang ini, dan aku telah diberikan kunci-kunci perbendaharaan bumi (atau kunci-kunci bumi). Demi Allah! Aku tidak takut bahawa kamu akan menyekutukan Allah dengan yang lain selepas kewafatanku, tetapi aku takut kamu akan berebut-rebut antara satu sama lain demi perkara-perkara dunia."(Sahih Bukhari)

Narrated 'Uqbah Ibn 'Amir (May Allah be pleased with him): One day the Prophet (Peace be upon him) went out and offered the funeral prayers of the martyrs of Uhud and then went up the pulpit and said: "I will pave the way for you as your predecessor and will be a witness on you. By Allah! I see my Fount (Kauthar) just now and I have been given the keys of all the treasures of the earth (or the keys of the earth). By Allah! I am not afraid that you will worship others along with Allah after my death, but I am afraid that you will fight with one another for the worldly things.”(Sahih Bukhari)

Abu Hurairah (semoga Allah meridhainya) meriwayatkan: Sesungguhnya Rasulullah ﷺ bersabda: Sesungguhnya Telagaku mempunyai ukuran yang lebih luas daripada jarak antara Aila (Baitul Maqdis) dan Aden, airnya lebih putih daripada salju dan lebih manis daripada madu yang dicampur dengan susu, dan cawan-cawannya lebih banyak daripada bilangan bintang-bintang. Sesungguhnya aku akan menghalau orang-orang (yang tidak beriman) di sana sebagaimana seseorang menghalau unta-unta orang lain dari mata airnya. Mereka bertanya: Wahai Rasulullah ﷺ, adakah engkau akan mengenali kami pada hari itu? Baginda bersabda: Ya, kamu akan mempunyai tanda-tanda khusus yang tidak dimiliki oleh mana-mana umat lain (selain kamu), kamu akan datang kepadaku dengan dahi yang bercahaya dan tangan serta kaki yang bersinar akibat bekas wuduk." (Sahih Bukhari)

Abu Hurairah (May Allah be pleased with him) reported: Verily Allah's Messenger (Peace be upon him) said: My Cistern has its dimensions wider than the distance between Aila (Jerusalem) and Aden, and its water is whiter than ice and sweeter than the honeydiluted with milk, and its cups are more numerous than the numbers of the stars. Verily I shall prevent the (faithless) people there from just as a man prevents the camels of the people from his fountain. They said: Messenger of Allah, will you recognize us on that day? He said: Yes, you will have distinctive marks which nobody among the peoples (except you) will have,' you would come to me with blazing forehead and bright hands and feet on account of the traces of ablution." (Sahih Bukhari)

Diriwayatkan daripada Anas (semoga Allah meredainya): Ketika Nabi ﷺ dinaikkan ke langit, baginda ﷺ bersabda (selepas kembali), "Aku sampai ke sebuah sungai (di dalam Syurga) yang tebingnya dibuat daripada khemah-khemah mutiara berongga. Aku bertanya kepada Jibril (Gabriel), 'Apakah ini (sungai)?' Beliau menjawab, 'Inilah al-Kauthar.'" (Sahih Bukhari)

Narrated Anas (May Allah be pleased with him): When the Prophet (Peace be upon him) was made to ascend to the heavens. He (Peace be upon him) said (after his return), "I came upon a river (in Paradise) the banks of which were made of tents of hollow pearls. I asked Jibril (Gabriel), 'What is this (river)?' He replied, "This is the Kauthar.” (Sahih Bukhari)
