Musannaf Ibn Abi Shaybah 1158 — Ghusl with the water of a bathhouse

Abu Farwah said: I asked al-Sha'bi: Will you take a bath with the water of the bathhouse when you are in a state of major ritual impurity? He said: Yes, and then I will count it as my most thorough bath. I said: Will you take a bath again after coming out of the bathhouse? He said: Then why would I enter it?
