Seeking Blessing from the Water of Zamzam and Using It for Healing

Question:
Honorable Shaykh, I seek forgiveness from Allah. Is it permissible to seek blessing (tabarruk) with what is mentioned in the narrations regarding this? By seeking blessing, I mean seeking the source of blessing in matters of stubbornness and healing, after Allah (Glorified and Exalted is He).

Answer:
The water of Zamzam is to be used as the Prophet (peace and blessings be upon him) directed: it is to be drunk and used for gurgling. This is what the Prophet (peace and blessings be upon him) directed. As for using it for healing, this is not established. It was reported that it is a cure for illness, but this was not a statement of the Messenger (peace and blessings be upon him). Matters of tawhid (the oneness of Allah) are not established by weak narrations or stories. What is prescribed (mashru') in its meaning is drinking it and gurgling with it, following the Prophet (peace and blessings be upon him). This is what is prescribed.
