Musannaf Ibn Abi Shaybah 33815 — What Allah the Exalted gave Muhammad

Sayyiduna Anas (may Allah be pleased with him) said: While the Messenger of Allah (peace and blessings be upon him) was sitting among us, he dozed off for a moment. Then he raised his head smiling. We said: O Messenger of Allah (peace and blessings be upon him), what has happened to you? He said: A surah has just been revealed to me. And he (peace and blessings be upon him) recited: "In the name of Allah, the Most Gracious, the Most Merciful. Indeed, We have given you al-Kawthar. So pray to your Lord and sacrifice. Indeed, your enemy is the one cut off." Then he (peace and blessings be upon him) said: Do you know what al-Kawthar is? We said: Allah and His Messenger know best. He said: It is a river that my Lord has promised me; upon it there is much good, and it is a Pond to which my Ummah will come on the Day of Resurrection. Its vessels are as many as the stars. Then a servant will be held back from it, and I will say: O my Lord, indeed he is one of my companions. Allah Almighty will say: No, you do not know what innovation he has introduced after you.
