وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ لِبْسَتَيْنِ وَعَنْ بَيْعَتَيْنِ عَنِ الْمُلاَمَسَةِ وَعَنِ الْمُنَابَذَةِ وَعَنْ أَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَىْءٌ وَعَنْ أَنْ يَشْتَمِلَ الرَّجُلُ بِالثَّوْبِ الْوَاحِدِ عَلَى أَحَدِ شِقَّيْهِ ‏.‏

Yahya related to me from Malik from Abu'z-Zinad from al-Araj thatAbu Hurayra said, "The Messenger of Allah, may Allah bless him andgrant him peace, forbade two sales. Mulamasa, in which a man isobliged to buy whatever he touches without any choice in the matter,and munabadha, in which two men throw their garment to each otherwithout either seeing the other's garment. He also forbade two ways ofdressing. One in which a man sits with his legs drawn up to his chestwrapped in one garment that does not cover his genitals, and the otherin which a man wraps a single garment over one arm and shoulderrestricting them."
