Musnad Abu Ya'la al-Mawsili 209:153

Abu Khaythama narrated to us, al-Hasan ibn Musa narrated to us, Ibn Lahi'ah narrated to us, Darraj narrated from al-Sa'ib, the freed slave of Umm Salamah, that some women from the people of Homs entered upon Umm Salamah. She asked them, "From whom are you?" They said, "From the people of Homs." She said, "I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: 'Any woman who removes her garments in other than her house, Allah removes His covering from her.'"
