The Description of al-Kawthar

Al-Bukhari then said: It has also been narrated by Zakariyya, Abu al-Ahwas, and Mutarrif, from Abu Ishaq. And Abu Nu'aym al-Fadl ibn Dukayn said: Ibn Abi Najih narrated to us, from Mujahid, who said: "It is Paradise."

And 'A'ishah (may Allah be pleased with her) said:

"It is a river in Paradise; no one places his two fingers into his ears except that he hears the murmur of that river."

Ibn Jarir narrated from Abu Kurayb, from Waki', from Abu Ja'far al-Razi, from Ibn Abi Najih, from 'A'ishah (may Allah be pleased with her), who said:

"Whoever wishes to hear the murmur of al-Kawthar (meaning the sound of its flowing waters), he cannot hear it directly in its reality, but its resonance is like that which one hears when a person inserts his two fingers into his ears."
