Fasting
Keeping the Fast free from Imperfection - Section 2
عَن عَائِشَة: أَن الني صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: كَانَ يُقَبِّلُهَا وَهُوَ صَائِم ويمص لسنانها. رَوَاهُ أَبُو دَاوُد
‘A'isha said that the Prophet (ﷺ) used to kiss her and suck her tongue when he was fasting. Abu Dawud transmitted it.* *Saum, 34. This is said by some to be weak because Muhammad b. Dinar and Sa'd b. Aus are among its transmitters.
