Anas bin Malik said: The Messenger of Allah صلی اللہ علیہ وسلم dozed for a short while and raised his smiling. He either said to them (people) or they said to him: Messenger of Allah! Why did you laugh? He said: A surah has been revealed to me just now, and then he recited:“In the name of Allah, Most Gracious. Most Merciful. To thee We have granted the fount (of abundance)”up to the end. When he recited, he asked: Do you know what al-kauthar is? They replied: Allah and his Messenger know best. He said: It is a river which my Lord, the Exalted, has promised me (to grant) in Paradise: there is abundance of good and upon it there is a pond which my people will approach on the Day of Resurrection. There are vessels as numerous as stars (in the sky).
