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
