What did the wife of `Umar bin Al-Khattab quote when she was asked why she attended the congregational prayers in the mosque, even though `Umar (bin Al-Khattab) disliked it?
 Narrated Ibn `Umar:                     One of the wives of `Umar (bin Al-Khattab) used to offer the Fajr and the `Isha' prayer in congregation in the Mosque. She was asked why she had come out for the prayer as she knew that `Umar disliked it, and he has great ghaira (self-respect). She replied, "What prevents him from stopping me from this act?" The other replied, "The statement of Allah's Apostle (p.b.u.h) : 'Do not stop Allah's women-slave from going to Allah s Mosques' prevents him."
