(Imām Bukhārī narrates): Yusuf bin Musa narrated the hadith to us, he said: Abu Usamah narrated the hadith to us, he said: Ubaidullah bin Umar narrated the hadith to us from Nafi from Ibn Umar, he narrated that

the wife of Hazrat Umar used to go to the mosque to offer the morning and the night prayer with congregation. It was said to her: Why do you go out, while you know that Hazrat Umar dislikes your going out and he feels protective jealousy over it? She said: Then what prevents him from forbidding me? Hazrat Ibn Umar said: What prevents him from forbidding her is this saying of the Messenger of Allah ﷺ: do not forbid the female servants of Allah from going to the mosques of Allah.
