It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Among the men of my Ummah, whoever believes in Allah and the Last Day should not enter the bathhouse without a lower garment, and among the women of my Ummah, whoever believes in Allah and the Last Day should not enter the bathhouse at all.
