Muwatta Malik, Book 14, Hadith 471 (In-Book)

Yahya related to me from Malik from Yahya ibn Said that Atika bint Zayd ibn Amr ibn Nufayl, the wife of Umar ibn al-Khattab, used to ask Umar ibn al-Khattab for permission to go to the mosque. He would keep silent, so she would say, "By Allah, I will go out, unless you forbid me," and he would not forbid her.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَاتِكَةَ بِنْتِ زَيْدِ بْنِ عَمْرِو بْنِ نُفَيْلٍ، امْرَأَةِ عُمَرَ بْنِ الْخَطَّابِ أَنَّهَا كَانَتْ تَسْتَأْذِنُ عُمَرَ بْنَ الْخَطَّابِ إِلَى الْمَسْجِدِ فَيَسْكُتُ فَتَقُولُ وَاللَّهِ لأَخْرُجَنَّ إِلاَّ أَنْ تَمْنَعَنِي ‏.‏ فَلاَ يَمْنَعُهَا ‏.‏
