[Machine] Be the handmaidens of Omar, who served us as healers revealing their emotions and striking their chests. The sheikh said, "The narrations from Omar bin Al-Khattab in this regard are authentic and indicate that her head, neck, and what is visible of her in a time of distress should not be considered an 'awrah (a part of the body that should be covered)." As for the hadith of Amr bin Shu'ayb, there is disagreement concerning its content, so it should not be relied upon when determining the 'awrah of a woman. However, it can be used as evidence along with other similar narrations when determining the 'awrah of a man.

And with Allah is the success. Some of our companions have used a hadith as evidence in this matter.  

كُنَّ إِمَاءُ عُمَرَ ؓ يَخْدِمْنَنَا كَاشِفَاتٍ عَنْ شُعُورِهِنَّ تَضْرِبُ ثُدِيُّهُنَّ قَالَ الشَّيْخُ وَالْآثَارُ عَنْ عُمَرَ بْنِ الْخَطَّابِ ؓ فِي ذَلِكَ صَحِيحَةٌ وَإِنَّهَا تَدُلُّ عَلَى أَنَّ رَأْسَهَا وَرَقَبَتَهَا وَمَا يَظْهَرُ مِنْهَا فِي حَالِ الْمِحْنَةِ لَيْسَ بِعَوْرَةٍ فَأَمَّا حَدِيثُ عَمْرِو بْنِ شُعَيْبٍ فَقَدِ اخْتُلِفَ فِي مَتْنِهِ فَلَا يَنْبَغِي أَنْ يُعْتَمَدَ عَلَيْهِ فِي عَوْرَةِ الْأَمَةِ وَإِنْ كَانَ يَصْلُحُ الِاسْتِدْلَالُ بِهِ وَبِسَائِرِ مَا يَأْتِي عَلَيْهِ مَعَهُ فِي عَوْرَةِ الرَّجُلِ وَبِاللهِ التَّوْفِيقُ وَقَدِ احْتَجَّ بَعْضُ أَصْحَابِنَا فِي ذَلِكَ بِحَدِيثٍ
