باب النَّهْىِ عَنِ اشْتِمَالِ الصَّمَّاءِ، وَالاِحْتِبَاءِ، فِي ثَوْبٍ وَاحِدٍ ‏.‏
Sahih Muslim 2099 a

Jabir reported that Allah's Messenger (ﷺ) forbade that a man should eat with the left hand or walk with one sandal or wrap himself completely leaving no opening for the arms (to draw out) or support himself when sitting with a single garment wrapped round his knees which may expose his private parts.

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكِ بْنِ أَنَسٍ، - فِيمَا قُرِئَ عَلَيْهِ - عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى أَنْ يَأْكُلَ الرَّجُلَ بِشِمَالِهِ أَوْ يَمْشِيَ فِي نَعْلٍ وَاحِدَةٍ وَأَنْ يَشْتَمِلَ الصَّمَّاءَ وَأَنْ يَحْتَبِيَ فِي ثَوْبٍ وَاحِدٍ كَاشِفًا عَنْ فَرْجِهِ ‏.‏
