Sunan Abi Dawud 4080
Narrated AbuHurayrah:
The Messenger of Allah (ﷺ) forbade wearing clothes in two styles: that a man sits in a single garment with his hands round his knees and uncover his private parts towards heaven and that he wears his garment while one of his sides is uncovered, and puts the garment on his shoulders.
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ لِبْسَتَيْنِ أَنْ يَحْتَبِيَ الرَّجُلُ مُفْضِيًا بِفَرْجِهِ إِلَى السَّمَاءِ وَيَلْبَسَ ثَوْبَهُ وَأَحَدُ جَانِبَيْهِ خَارِجٌ وَيُلْقِي ثَوْبَهُ عَلَى عَاتِقِهِ ‏.‏
