And Zuhayr ibn Harb and Abu Ghassan al-Misma'i narrated to me — and Muhammad ibn al-Muthanna and Ibn Bashshar also narrated it to us — they said: Mu'adh ibn Hisham narrated to us, he said: my father narrated to me, from Qatadah and Matar, from al-Hasan, from Abu Rafi', from Abu Hurayrah, that the Prophet of Allah, peace and blessings be upon him, said: "When he sits between her four parts, then exerts himself upon her, then bathing (ghusl) has become obligatory upon him." And in the hadith of Matar: "Even if he does not ejaculate." Zuhayr said, among them: "Between her four parts (asha'ubiha al-arba')."
