Narrated Jabir bin 'Abdullah (RA):

The Prophet (ﷺ) forbade Muhaqalah, Muzabanah, and Mukhabarah. He also forbade Thunya unless it was explicit (a known amount). [Reported by al-Khamsah excluding Ibn Majah; at-Tirmidhi graded it Sahih (authentic)].

وَعَنْ جَابِرِ بْنِ عَبْدِ اَللَّهِ ‏-رَضِيَ اَللَّهُ عَنْهُمَا‏-; { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-نَهَى عَنْ اَلْمُحَاقَلَةِ, وَالْمُزَابَنَةِ, وَالْمُخَابَرَةِ, وَعَنْ اَلثُّنْيَا, إِلَّا أَنْ تُعْلَمَ } رَوَاهُ اَلْخَمْسَةُ إِلَّا اِبْنَ مَاجَهْ, وَصَحَّحَهُ اَلتِّرْمِذِيُّ [1]‏ .‏
