The ruling on Zamzam water outside the Haram and the supplication when drinking it

Question:
Some people say that when Zamzam water leaves the Haram, its benefit is lost. Is this correct? And what is the supplication recited when drinking it?

Answer:
This is not correct. Zamzam water is Zamzam water; it is blessed water in Makkah and in other lands. It is Zamzam water, and in it is what the Prophet (peace and blessings be upon him) said: It is blessed water. The supplication is: one says, "O Allah," naming it, saying "In the name of Allah," and saying, "O Allah, O Allah, make it beneficial knowledge, righteous action, and a cure for every disease. Wash my heart with it and fill it with the fear of You."
