Reason Necessitating Ghusl (bath) for Men and Women

5. A number of our people have narrated from Ahmad ibn Muhammad from Tsma‘il ibn Sa‘d al-Ash’ariy who has said the following: “I once asked al-Rida, Alayhi al-Salam, about a man who touches and plays by his hand with the private parts of his slave-girl without contact of his private part until she feels discharge, is Ghusl (bath) necessary on her? He (the Imam) said, ‘Ghusl (bath) is necessary if discharge is accompanied by orgasm.’”
