Hadith 7:30
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
