Narrated Anas bin Malik: The Prophet said: "While I was walking in Paradise (on the night of Mi'raj), I saw a river, on the two banks of which there were tents made of hollow pearls. I asked, "What is this, O Gabriel?' He said, 'That is the Kauthar which Your Lord has given to you.' Behold! Its scent or its mud was sharp smelling musk!" (The sub-narrator, Hudba is in doubt as to the correct expression.)

Narrated Sharik bin `Abdullah bin Abi Namr: I heard Anas bin Malik telling us about the night when the Prophet was made to travel from the Ka`ba Mosque. Three persons (i.e. angels) came to the Prophet before he was divinely inspired was an Aspostle), while he was sleeping in Al Masjid-ul-Haram. The first (of the three angels) said, "Which of them is he?" The second said, "He is the best of them." That was all that happened then, and he did not see them till they came at another night and he perceived their presence with his heart, for the eyes of the Prophet were closed when he was asleep, but his heart was not asleep (not unconscious). This is characteristic of all the prophets: Their eyes sleep but their hearts do not sleep. Then Gabriel took charge of the Prophet and ascended along with him to the Heaven.

Narrated Anas: When the Prophet was made to ascend to the Heavens, he said (after his return), "I came upon a river the banks of which were made of tents of hollow pearls. I asked Gabriel. What is this (river?' He replied, 'This is the Kauthar.'

Narrated Abu Ubaida: I asked `Aisha 'regarding the verse:--'Verily we have granted you the Kauthar.' She replied, "The Kauthar is a river which has been given to your Prophet on the banks of which there are (tents of) hollow pearls and its utensils are as numberless as the stars."

Narrated Ibn `Abbas: The word 'Al-Kauthar' means the abundant good which Allah gave to him (the Prophet Muhammad). Abu Bishr said: I said to Sa`id, "Some people claim that it (Al-Kauthar) is a river in Paradise." Sa`id replied, "The river which is in Paradise is one item of that good which Allah has bestowed upon him (Muhammad).
