It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) went to visit Sayyidah Umm Ayman (may Allah be pleased with her), and I was with him. She brought something to drink near to him (peace and blessings be upon him); either he was fasting or he did not want it, so he (peace and blessings be upon him) returned it, and she began to scold the Messenger of Allah (peace and blessings be upon him). After the death of the Prophet (peace and blessings be upon him), Sayyiduna Abu Bakr (may Allah be pleased with him) said to Sayyiduna Umar (may Allah be pleased with him): "Come with us to visit Sayyidah Umm Ayman (may Allah be pleased with her)." When they came to her, she began to weep. They both said: "Why do you weep? What is with Allah Almighty is better for His Messenger (peace and blessings be upon him)." She said: "I do not weep because I do not know this; rather, I weep because the revelation from the heavens has now stopped." After she said this, Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both) also began to weep.
