What may be used to cover the private parts of the body

Narrated Abu Said Al-Khudri

Allah's Apostle forbade Ishtimal-As-Samma' (wrapping one's body with a garment so that one cannot raise its end or take one's hand out of it). He also forbade Al-Ihtiba' (sitting on buttocks with knees close to abdomen and feet apart with the hands circling the knees) while wrapping oneself with a single garment, without having a part of it over the private parts.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا لَيْثٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّهُ قَالَ نَهَى رَسُولُ اللَّهِ ﷺ عَنِ اشْتِمَالِ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ، لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَىْءٌ.

Narrated Abu Huraira:

The Prophet forbade two kinds of sales i.e. Al-Limais and An-Nibadh (the former is a kind of sale in which the deal is completed if the buyer touches a thing, without seeing or checking it properly and the latter is a kind of a sale in which the deal is completed when the seller throws a thing towards the buyer giving him no opportunity to see, touch or check it) and (the Prophet forbade) also Ishtimal-As-Samma' and Al-Ihtiba' in a single garment.

حَدَّثَنَا قَبِيصَةُ بْنُ عُقْبَةَ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ نَهَى النَّبِيُّ ﷺ عَنْ بَيْعَتَيْنِ عَنِ اللِّمَاسِ وَالنِّبَاذِ، وَأَنْ يَشْتَمِلَ الصَّمَّاءَ، وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ.
