Jabir reported that Messenger of Allah ﷺ forbade the wrapping of oneself completely leaving no room for the arm and supporting oneself when sitting with a single garment wrapped round one's knees and a person raising one of his feet and placing it on the other while lying on his back.
أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنِ اشْتِمَالِ الصَّمَّاءِ وَالاِحْتِبَاءِ فِي ثَوْبٍ وَاحِدٍ وَأَنْ يَرْفَعَ الرَّجُلُ إِحْدَى رِجْلَيْهِ عَلَى الأُخْرَى وَهُوَ مُسْتَلْقٍ عَلَى ظَهْرِهِ
