Sahih al-Bukhari 1215

Arabic

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ ـ رضى الله عنه ـ قَالَ كَانَ النَّاسُ يُصَلُّونَ مَعَ النَّبِيِّ صلى الله عليه وسلم وَهُمْ عَاقِدُو أُزْرِهِمْ مِنَ الصِّغَرِ عَلَى رِقَابِهِمْ، فَقِيلَ لِلنِّسَاءِ ‏ "‏ لاَ تَرْفَعْنَ رُءُوسَكُنَّ حَتَّى يَسْتَوِيَ الرِّجَالُ جُلُوسًا ‏"‏‏.‏

English translation

Narrated Sahl bin Sa`d:The people used to offer the prayer with the Prophet (ﷺ) with their waist-sheets tied round their necks because of the shortness of the sheets and the women were ordered not to lift their heads till the men had sat straight
