The Hawd is the great Pool granted to the Prophet ﷺ on the Day of Judgment, and its water is connected to al-Kawthar, the river Allah gave him in Paradise (Quran 108:1). The Prophet said his Hawd is the distance of a month's journey, its water whiter than milk and sweeter than honey, its cups as numerous as the stars, and whoever drinks from it will never thirst again. His believing followers who kept to his Sunnah will be given to drink, while some who altered the religion after him will be driven away from it. Affirming the Hawd is part of the creed of Ahl al-Sunnah, established by mass-transmitted (mutawatir) narrations.
