Surah Al-Kawthar is the 108th surah of the Qur'an, with three verses the shortest one. There are several differing opinions as to the circumstances under which it was revealed. According to Ibn- Ishaq, it was revealed in Mecca, sometime before the Isra and Miraj.
Tradition has it that Al-Kawthar (from a root meaning "the river in paradise"), a word that occurs only once in the Qur'an, is the name of a river in Paradise. On Yaum al-Qiyamah (the Day of Judgement) all of those who truly believe in Allah will be led to Al-Kawthar where they will drink only once, and will never hunger or thirst again.
