Praying in an izar (waist wrap)

It was narrated that Sahl bin Sa'd said:

"Some men used to pray with Messenger of Allah(ﷺ) 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 ‏.‏

It was narrated that 'Amr bin Salamah said:

"When my people came back from the Prophet (ﷺ)they said that he had said: 'Let the one who recites the Quran most lead you in prayer.' So they called me and taught me how to bow and prostrate, and I used to lead them in prayer, wearing a torn cloak, and they used to say to my father: 'Will you not conceal your son's backside from us?"'

أَخْبَرَنَا شُعَيْبُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، قَالَ أَنْبَأَنَا عَاصِمٌ، عَنْ عَمْرِو بْنِ سَلِمَةَ، قَالَ لَمَّا رَجَعَ قَوْمِي مِنْ عِنْدِ النَّبِيِّ صلى الله عليه وسلم قَالُوا إِنَّهُ قَالَ ‏

‏ لِيَؤُمَّكُمْ أَكْثَرُكُمْ قِرَاءَةً لِلْقُرْآنِ ‏

‏ ‏.‏ قَالَ فَدَعَوْنِي فَعَلَّمُونِي الرُّكُوعَ وَالسُّجُودَ فَكُنْتُ أُصَلِّي بِهِمْ وَكَانَتْ عَلَىَّ بُرْدَةٌ مَفْتُوقَةٌ فَكَانُوا يَقُولُونَ لأَبِي أَلاَ تُغَطِّي عَنَّا اسْتَ ابْنِكَ ‏.‏
