To make the Heart Tender (Ar-Riqaq)

Narrated Jundab: I heard the Prophet, saying, "I am your predecessor at the Lake-Fount. (Al-Kauthar) .

Narrated `Uqba bin 'Amir: Once the Prophet went out and offered the funeral prayers for the martyrs of Uhud, and then went to the pulpit and said, "I am a predecessor for you and I am a witness for you: and by Allah, I am looking at my Fount just now, and the keys of the treasures of the earth (or the keys of the earth) have been given to me: and by Allah, I am not afraid that you will worship others besides Allah after me, but I am afraid that you will strive and struggle against each other over these treasures of the world."

Narrated Haritha bin Wahb: I heard the Prophet mentioning the Lake-Fount (Al-Kauthar), saying, "(The width of the Lake-Fount) is equal to the distance between Medina and Sana' (capital of Yemen)." Haritha said that he heard the Prophet saying that his Lake-Fount would be as large as the distance between Sana' and Medina. Al- Mustaurid said to Haritha, "Didn't you hear him talking about the vessels?" He said, "No." Al- Mustaurid said, "The vessels are seen in it as (numberless as) the stars."

Narrated Asma 'bint Abu Bakr: The Prophet said, "I will be standing at the Lake-Fount so that I will see whom among you will come to me; and some people will be taken away from me, and I will say, 'O Lord, (they are) from me and from my followers.' Then it will be said, 'Did you notice what they did after you? By Allah, they kept on turning on their heels (turned as renegades).' " The sub-narrator, Ibn Abi Mulaika said, "O Allah, we seek refuge with You from turning on our heels, or being put to trial in our religion."
