[Machine] The Messenger of Allah ﷺ forbade wearing two garments at the same time, and wearing clothes with long tails that trail on the ground or that are gathered up and tucked under the waist, causing the private parts to be exposed towards the sky. As for the two "bay'atain" (pieces of clothing or garments), it refers to throwing them to me or to you, and throwing stones.
نَهَى رَسُولُ اللهِ ﷺ عَنْ لُبْسَتَيْنِ وَعَنْبَيْعَتَيْنِ فَأَمَّا اللُّبْسَتَانِ فَأَنْ يَتَلَحَّفَ بِثَوْبِهِ وَيُخْرِجُ شِقَّهُ أَوْ يَحْتَبِي بِثَوْبٍ وَاحِدٍ فَيُفْضِي بِفَرْجِهِ إِلَى السَّمَاءِ وَأَمَّا الْبَيْعَتَانِ فَالْمُلَامَسَةُ أَلْقِ إِلَيَّ وَأُلْقِ إِلَيْكَ وَإلْقَاءُ الْحَجَرِ
