Narrated Jabir: "The Messenger of Allah prohibited Ishtimal As-Samma, Al-Ihtiba in one garment, and that a man raise one of his feet atop the other while he is reclining on his back."
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا اللَّيْثُ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ اشْتِمَالِ الصَّمَّاءِ وَالاِحْتِبَاءِ فِي ثَوْبٍ وَاحِدٍ وَأَنْ يَرْفَعَ الرَّجُلُ إِحْدَى رِجْلَيْهِ عَلَى الأُخْرَى وَهُوَ مُسْتَلْقٍ عَلَى ظَهْرِهِ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
