Hazrat Umme Ummaarah (ra) was extremely devoted to the Holy Prophet (sas) and was always ready to sacrifice her life for him. The Holy Prophet (sas) was also very affectionate with her. Once when the Holy Prophet (sas) was visiting her, Hazrat Umme Ummaarah (ra) offered him food. The Holy Prophet (sas) asked her to join him. She said, “Messenger of Allah! I am fasting.” The Holy Prophet (sas) said, “Angels send Durood on those who fast if a person eats in front of them.” Then, he (sas) ate in front of Hazrat Umme Ummaarah (ra). After the demise of the Holy Prophet (sas), Hazrat Abu Bakr (ra) also used to visit her and inquire after her.1
