All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Whoever possesses Zamzam water by having put it in a container and the like, he is allowed to sell it and act in its regard in any permissible manner. As regards selling Zamzam water at its source without possessing it and without putting it in containers and the like, then this is not permissible because it is a public property.
We hope that the issue is clear now.
Allaah Knows best.
