Ishaq narrated to us, al-Nadr narrated to us, Shu'bah narrated to us, from Sa'd ibn Ibrahim, who said: I heard Talhah ibn Ubayd Allah say: I heard 'Aishah say: The Messenger of Allah (may Allah bless him and grant him peace) leaned toward me to kiss me while I was fasting. I said: "I am fasting." He said: "And I am fasting," then he kissed me.
