Sunan an-Nasa'i, Hadith 4513 ⓘ
Abu Hurairah said: "The Messenger of Allah forbade Munabadhah and Mulamash. Mulamasah is when two men trade garments with each other under cover of night, each man touching the garment of the other with his hand> and Munabadhah is when one man throws a garment to another and the other throws a garment to him, and they trade them with each other in that manner."
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُصَفَّى بْنِ بُهْلُولٍ، عَنْ مُحَمَّدِ بْنِ حَرْبٍ، عَنِ الزُّبَيْدِيِّ، عَنِ الزُّهْرِيِّ، قَالَ سَمِعْتُ سَعِيدًا، يَقُولُ سَمِعْتُ أَبَا هُرَيْرَةَ، يَقُولُ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الْمُلاَمَسَةِ وَالْمُنَابَذَةِ وَالْمُلاَمَسَةُ أَنْ يَتَبَايَعَ الرَّجُلاَنِ بِالثَّوْبَيْنِ تَحْتَ اللَّيْلِ يَلْمِسُ كُلُّ رَجُلٍ مِنْهُمَا ثَوْبَ صَاحِبِهِ بِيَدِهِ وَالْمُنَابَذَةُ أَنْ يَنْبِذَ الرَّجُلُ إِلَى الرَّجُلِ الثَّوْبَ وَيَنْبُذَ الآخَرُ إِلَيْهِ الثَّوْبَ فَيَتَبَايَعَا عَلَى ذَلِكَ .
