Musannaf Ibn Abi Shaybah 787 — A man who enters a state of janabah

Al-Awza'i said: I asked al-Zuhri: "If a man is in a state of janabah and has only enough water to perform ablution, what should he do?" He said: "He should perform tayammum." Abdah bin Abi Lubabah said: "He should perform ablution and also perform tayammum."
