Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "If I have intimacy with my wife at night and then deliberately leave the ritual bath (ghusl) until true dawn comes, this will not prevent me from fasting, because when I had intimacy with that woman she was lawful for me."
Al-Tabarani recorded it in al-Mu'jam al-Kabir. I have not found anyone who mentions the narrator Yahya bin al-Harith. The rest of the narrators of this report are the narrators of the Sahih.
