عَن عَائِشَة
أَن الني صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: كَانَ يُقَبِّلُهَا وَهُوَ صَائِم ويمص لسنانها
Aishah said that the Prophet (sallallahu alayhi wa sallam) 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 ibn Dinar and Sad ibn Aus are among its transmitters.
