The tradition mentioned above has also been reported by Abu Sa'id al-Khudri from the Prophet ﷺ through a different chain of narrators. This version adds:
"Wearing the samma' means that a man puts his garment over his left shoulder and keeps his right side uncovered. Munabadhah means that a man says (to another): If I throw this garment to you, the sale will be certain. Mulamasah means that a man touches it (another's garment) with his hand and neither he unfolds it nor turns it over. When he touched it, the sale becomes binding.

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عَطَاءِ بْنِ يَزِيدَ اللَّيْثِيِّ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ زَادَ وَاشْتِمَالُ الصَّمَّاءِ أَنْ يَشْتَمِلَ فِي ثَوْبٍ وَاحِدٍ يَضَعُ طَرَفَىِ الثَّوْبِ عَلَى عَاتِقِهِ الأَيْسَرِ وَيُبْرِزُ شِقَّهُ الأَيْمَنَ وَالْمُنَابَذَةُ أَنْ يَقُولَ إِذَا نَبَذْتُ إِلَيْكَ هَذَا الثَّوْبَ فَقَدْ وَجَبَ الْبَيْعُ وَالْمُلاَمَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلاَ يَنْشُرُهُ وَلاَ يُقَلِّبُهُ فَإِذَا مَسَّهُ وَجَبَ الْبَيْعُ .
