Abu Qays (may Allah have mercy on him) narrates that Abdullah bin Amr bin al-As (may Allah be pleased with him) sent him to Sayyidah Umm Salamah (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him), to ask whether the Messenger of Allah (peace and blessings be upon him) used to kiss while fasting, (saying:) "If she says: No, then say to her: Sayyidah Aishah (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) used to kiss while fasting." Abu Qays said: So I came to Sayyidah Umm Salamah (may Allah be pleased with her), and she asked: "Are you free or a slave?" I said: "Rather, a slave." She said: "Come closer." I came closer and said: "Abdullah bin Amr (may Allah be pleased with him) has sent me to you to ask whether the Messenger of Allah (peace and blessings be upon him) used to kiss while fasting." She said: "No." I said: "Sayyidah Aishah (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) used to kiss while fasting." She said: "Perhaps, because of his love for her, he (peace and blessings be upon him) could not restrain himself."
