Hadith 1215
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ ، أَخْبَرَنَا سُفْيَانُ ، عَنْ أَبِي حَازِمٍ ، عَنْ سَهْلِ بْنِ سَعْدٍ رَضِيَ اللَّهُ عَنْهُ , قَالَ : " كَانَ النَّاسُ يُصَلُّونَ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُمْ عَاقِدُو أُزْرِهِمْ مِنَ الصِّغَرِ عَلَى رِقَابِهِمْ ، فَقِيلَ لِلنِّسَاءِ : لَا تَرْفَعْنَ رُءُوسَكُنَّ حَتَّى يَسْتَوِيَ الرِّجَالُ جُلُوسًا " .
Narrated Sahl bin Sa`d: The people used to offer the prayer with the Prophet 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.
