Sunan an-Nasa'i, Volume 1, Book 9, Hadith 767 (DarusSalam) ⓘ

It was narrated that Sahl bin Sa'd said: "Some men used to pray with Messenger of Allah tying their lower garments tight like children, it was said to the women: 'Do not raise your heads until the men have sat up completely.'"

أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، قَالَ حَدَّثَنِي أَبُو حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ، قَالَ كَانَ رِجَالٌ يُصَلُّونَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم عَاقِدِينَ أُزْرَهُمْ كَهَيْئَةِ الصِّبْيَانِ فَقِيلَ لِلنِّسَاءِ لاَ تَرْفَعْنَ رُءُوسَكُنَّ حَتَّى يَسْتَوِيَ الرِّجَالُ جُلُوسًا ‏.‏
