It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The best water on the face of the earth is the water of Zamzam; in it is the nourishment of food and a cure for illness. And by Allah, there is no water on the face of the earth worse than the water of a well in the valley of Barahut; (the creatures living in it) are like vermin resembling the legs of locusts. In the morning it overflows, and in the evening there is not even moisture in it."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ibrahim bin Abi Hurrah except Muhammad bin Muhajir, and no one narrated it from Muhammad bin Muhajir except Miskin bin Bukayr; al-Hasan bin Ahmad bin Abi Shu'ayb is alone in narrating it."
