Musnad Abu Ya'la al-Mawsili 209:80

Dāwūd ibn ‘Amr ibn Zuhayr al-Ḍabbī narrated to us, Sufyān narrated to us, from ‘Amr, from a man among the children of Umm Salamah, whose name was Salamah ibn ‘Umar ibn Abī Salamah, who said: Umm Salamah said: "O Messenger of Allah, I do not hear Allah mentioning women regarding the Hijrah." So Allah, the Mighty and Majestic, revealed: "And their Lord responded to them, 'Never will I allow to be lost the work of any worker among you, whether male or female.'" to the end of the verse. Dāwūd said: Sufyān said: "By this verse, the Khawārij emerged, and by it, the women emerged."
