Nasr ibn Ali al-Jahdhami and Muhammad ibn Bahr narrated to us, they said: Abu Raja’ Rawh ibn al-Musayyib al-Kalbi narrated to us, he narrated from Thabit, from Anas, who said: The women came to the Prophet, may Allah bless him and grant him peace, and said: "O Messenger of Allah, the men have taken away the virtue through Jihad in the way of Allah, so what deed do we have by which we may attain the deed of the Mujahideen in the way of Allah?" He said: "The service of one of you in her house attains the deed of the Mujahideen in the way of Allah."
