Hadith 7:134
Narrated Abu Hurairah (RA):
Allah's Messenger (ﷺ) said: "Give back what has been entrusted (to you) to him who has entrusted you, and do not violate the trust of him who violates your trust." [Reported by at-Tirmidhi and Abu Dawud; at-Tirmidhi graded it Hasan (good) and al-Hakim graded it Sahih (authentic). Abu Hatim ar-Razi considered it Munkar (rejected)].
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ أَدِّ اَلْأَمَانَةَ إِلَى مَنْ اِئْتَمَنَكَ, وَلَا تَخُنْ مَنْ خَانَكَ } رَوَاهُ أَبُو دَاوُدَ, وَاَلتِّرْمِذِيُّ وَحَسَّنَهُ, وَصَحَّحَهُ اَلْحَاكِمُ, وَاسْتَنْكَرَهُ أَبُو حَاتِمٍ اَلرَّازِيُّ
