From Sahih Bukhari (Hadith 315):
Narrated `Aisha:An Ansari woman asked the Prophet (ﷺ) how to take a bath after finishing from the menses. He replied, "Take a piece of cloth perfumed with musk and clean the private parts with it thrice." The Prophet (ﷺ) felt shy and turned his face. So I pulled her to me and told her what the Prophet (ﷺ) meant
