Aisha said, "Allah's Messenger (ﷺ) used to kiss some of his wives while he was fasting," and then she smiled.
Sahih al-Bukhari Book 30, Hadith 36
← Previous 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."

Sahih al-Bukhari Book 30, Hadith 35 Next Hadith → (daughter of Um Salama) that her mother said, "While I was (lying) with Allah's Messenger (ﷺ) underneath a woolen sheet, I got the menstruation, and then slipped away and put on the clothes (which I used to wear) in menses. He asked, "What is the matter? Did you get your menses?" I replied in the affirmative and then entered underneath that woolen sheet. I and Allah's Messenger (ﷺ) used to take a bath from one water pot and he used to kiss me while he was fasting."
