Musannaf Ibn Abi Shaybah

Hazrat Abu Farwah says that I asked Hazrat Sha’bi, “Would you perform ghusl (ritual bath) with the water of a public bath while in a state of janabah (major ritual impurity)?” He replied, “Yes, and then I would consider it my best ghusl.” I asked, “Would you perform ghusl again after coming out of the bath?” He replied, “Then why would I enter it in the first place?”
