Sunan Abi Dawud Book 2, Hadith 176
Ibn ‘Umar reported the Messenger of Allah (May peace be upon him) as saying; Do not prevent the female servant your women from visiting the mosques of Allah.
Do not prevent the female servants of Allah from visiting the mosques of Allah, but they may go out (to the mosque) having no perfumed themselves.
Ibn ‘Umar reported the Messenger of Allah (ﷺ) as saying; Do not prevent your women from visiting the mosque; but their houses are better for them (for praying).
