Imam al-Shafi'i (may Allah have mercy on him) said: "It has reached us that Sayyiduna Suhayl bin Amr (may Allah be pleased with him) sent some of it (Zamzam water) as a gift to the Prophet (peace and blessings be upon him)."
Imam al-Shafi'i (may Allah have mercy on him) further said: "And water is not something that, once gone, does not return."
