Takhrij Hadith 1418: "He saw a man drinking…"

He saw a man drinking from the water of Zamzam and said: "Do you know how to drink from the water of Zamzam?" The man asked: "And how should I drink from the water of Zamzam, O Abu 'Abbas?" He said: "When you want to drink from the water of Zamzam, draw a bucket from it, face the Qiblah, and say: 'In the name of Allah' (Bismillah). Breathe three times [outside the vessel while drinking], drink until you have had your fill, and say: 'O Allah, I ask You for beneficial knowledge, abundant provision, and a cure for every illness' (Allahumma inni as'aluka 'ilman nafi'an, wa-rizqan wasi'an, wa-shifa'an min kulli da')."
