4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad ibn ‘Uthman from ‘Ubayd Allah al-Halabiy who has said the following: “I once asked abu ‘Abd Allah, Alayhi al-Salam, about one’s foreplay and Ghusl (bath). He (the Imam) said, ‘There is Ghusl (bath) obligatory if semen discharge takes place.’”
