Abdullah bin Abbas reported,

The Messenger of Allah ﷺ said, "The best water on the face of the earth is the water of Zamzam. In it is nourishment that satisfies hunger and healing from sickness. The worst water on the face of the earth is the water in the valley of Barahut in Hadramawt. Vermin swarm over it like locusts. In the morning it gushes forth, and by evening not a drop of moisture remains in it."

عن ابن عباس، قال

قال رسول الله ﷺ: خير ماء على وجه الأرض ماء زمزم، فيه طعام من الطعم، وشفاء من السقم. وشر ماء على وجه الأرض ماء بوادي برهوت بحضرموت، عليه كرجل الجراد من الهوام، يصبح يتدفق ويمسي لا بلال فيه.
