Sahih Muslim 5671

حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ حَدَّثَنِي أَبِي عَنْ جَدِّي حَدَّثَنِي عُقَيْلُ بْنُ خَالِدٍ عَنْ ابْنِ شِهَابٍ عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ عَنْ عَائِشَةَ أَنَّ أَزْوَاجَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كُنَّ يَخْرُجْنَ بِاللَّيْلِ إِذَا تَبَرَّزْنَ إِلَى الْمَنَاصِعِ وَهُوَ صَعِيدٌ أَفْيَحُ وَكَانَ عُمَرُ بْنُ الْخَطَّابِ يَقُولُ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ احْجُبْ نِسَاءَكَ فَلَمْ يَكُنْ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَفْعَلُ فَخَرَجَتْ سَوْدَةُ بِنْتُ زَمْعَةَ زَوْجُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَيْلَةً مِنْ اللَّيَالِي عِشَاءً وَكَانَتْ امْرَأَةً طَوِيلَةً فَنَادَاهَا عُمَرُ أَلَا قَدْ عَرَفْنَاكِ يَا سَوْدَةُ حِرْصًا عَلَى أَنْ يُنْزَلَ الْحِجَابُ قَالَتْ عَائِشَةُ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ الْحِجَابَ

A'isha reported that the wives of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) used to go out in the cover of night when they went to open fields (in the outskirts of Medina) for easing themselves. 'Umar b Khattab used to say: Allah's Messenger, ask your ladies to observe veil, but Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) did not do that. So there went out Sauda, daughter of Zarn'a, the wife of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ), during one of the nights when it was dark. She was a tall statured lady. 'Umar called her saying: Sauda, we recognise you. (He did this with the hope that the verses pertaining to veil would be revealed.) 'A'isha said: Allah, the Exalted and Glorious, then revealed the verses pertaining to veil.
