He used to kiss her while fasting and suck her tongue. Ibn al-Arabi said, "This chain of narration is not authentic."
حدثنا محمد بن عيسى حدثنا محمد بن دينار حدثنا سعد بن أوس العبدي عن مصدع أبي يحيى
كان يقبلها وهو صائم ويمص لسانها قال ابن الأعرابي هذا الإسناد ليس بصحيح
[Its isnad is daif] Ahmad narrated it (6/123), and Ibn Khuzayma in his Sahih (no. 2003), from the hadith of Muhammad bin Dinar, and he is truthful, but he became confused in his later life. The rest of the chain is hasan.
