Sayyiduna Uthman Ghani (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) came to Zamzam and said: "Draw water. Were it not for the fear that you would be overcome regarding it (that is, the crowd would grow too large), I too would draw water."
Al-Bazzar recorded it; its chain contains a narrator, Sa'id bin Abd al-Malik bin Waqid. Abu Hatim says: "The hadith scholars have criticised him." He says: "I have seen that among the hadiths he narrated there are munkar (denounced) narrations."
