Musnad Ahmad 1153:2272

'Abd al-Wahhab narrated to us, from Sa'id, from Ayyub, from 'Abdullah ibn Shaqiq, from 'A'ishah—and Al-Khaffaf said another time: from Ibn 'Abbas—that the Prophet (peace and blessings of Allah be upon him) used to kiss while he was fasting. And Muhammad ibn Ja'far said—meaning in his hadith from Sa'id, from Ayyub, from 'Abdullah ibn Shaqiq, from Ibn 'Abbas—and Al-Khaffaf said the same another time.
