Mukhtasar Bukhari

`Sayyiduna Anas (may Allah be pleased with him) says that` when the Prophet Muhammad (peace and blessings be upon him) was taken up to the heavens (i.e., during the Mi'raj), he said: "I came to a river on whose banks were domed tents made of hollow pearls. I asked Jibreel (may Allah be pleased with him), 'What is this?' He replied, 'This is (your river) Kawthar.'"
