[Machine] The Messenger of Allah ﷺ prohibited wearing two garments at the same time. This means that a man should not wrap himself in one garment and then lift one side of it onto his shoulder, as there should not be any other garment over it. Nor should a man wrap himself in one garment in such a way that there is nothing between him and the sky, meaning that he is not covering himself.
نَهَى رَسُولُ اللهِ ﷺ عَنْ لِبْسَتَيْنِ الصَّمَّاءِ وَهُوَ أَنْ يَلْتَحِفَ الرَّجُلُ فِي الثَّوْبِ الْوَاحِدِ ثُمَّ يَرْفَعُ جَانِبَهُ عَلَى مَنْكِبِهِ لَيْسَ عَلَيْهِ ثَوْبٌ غَيْرَهُ أَوْ يَحْتَبِي الرَّجُلُ فِي الثَّوْبِ الْوَاحِدِ لَيْسَ بَيْنَهُ وَبَيْنَ السَّمَاءِ شَيْءٌ يَعْنِي سِتْرًا
