Musannaf Ibn Abi Shayba 1:1670

Yahya ibn Sa'id narrated to us, from Sufyan, from Zubayd, who said: I became in a state of major ritual impurity (janaba) and did not find water. So I asked Abu Atiyyah, and he said: "Do not pray." And I asked Sa'id ibn Jubayr, and he said: "Perform tayammum and pray."
