Surah Al-kawthar "Do you know what Al-Kawthar is?" They replied, "Allah and His Messenger know best." He said: "It is a river granted to me by my Lord, the Almighty, the All-Powerful in Paradise, in which is great goodness; its drinking vessels are as (limitless as) the heavenly bodies. It refuses to allow one of the slaves to drink, and the Prophet will say: 'Oh, my Lord! He is one of my community.' But it will be said to him: 'You know nothing of the innovations (in religion) that they practiced after you." You can check the Holy Qu'ran to read the full verse.
