عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنْ لِبْسَتَيْنِ وَعَنْ بَيْعَتَيْنِ، أَمَّا الْبَيْعَتَانِ الْمُلَامَسَةُ وَالْمُنَابَذَةُ، وَاللِّبْسَتَانِ اشْتِمَالُ الصَّمَّاءِ وَالْاِحْتِبَاءُ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَيْءٌ
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) forbade two types of clothing and two types of transactions. The two transactions are mulamasa and munabadhah, and the two types of clothing are: fastening a mute buckle and wrapping oneself in a single garment in such a way that one's private parts are not covered by any cloth.
