Sunan Abi Dawud 4081
Narrated Jabir:
The Messenger of Allah (ﷺ) forbade that a man should wrap himself completely in a garment with his hands hidden it, or sit in a single garment with his hands round his knees.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الصَّمَّاءِ وَعَنْ الاِحْتِبَاءِ فِي ثَوْبٍ وَاحِدٍ ‏.‏
