Mukhtasar Bukhari (Abridged) 1804 — Quranic Exegesis: Surah Al-Kawthar

It was asked from Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) about the saying of Allah, "We have granted you Al-Kawthar." She said that Al-Kawthar is a river which has been given to your Noble Prophet (peace be upon him). On its banks are domed pearls, and there are (cups) goblets placed there in the number of stars.
