At times Allah's Messenger (ﷺ) used to get up in the morning in the state of Janaba after having sexual relations with his wives. He would then take a bath and fast.
Sahih al-Bukhari Book 30, Hadith 34
← Previous Hadith Once the Prophet (ﷺ) ordered a person on 'Ashura' (the tenth of Muharram) to announce, "Whoever has eaten, should not eat any more, but fast, and who has not eaten should not eat, but complete his fast (till the end of the day).

Sahih al-Bukhari Book 30, Hadith 33 Next Hadith → The Prophet (ﷺ) used to kiss and embrace (his wives) while he was fasting, and he had more power to control his desires than any of you. Said Jabir, "The person who gets discharge after casting a look (on his wife) should complete his fast."
