Narrated 'Amr bin Dinar:
from a man among the children of Umm Salamah, from Umm Salamah that she said: "O Messenger of Allah! I have not heard Allah mentioning anything about women and emigration." So Allah, Blessed and Most High, revealed: "Never will I allow to be lost the work of any of you, be he male or female. You are members one of another (3:195)." (JA)
