Jami` at-Tirmidhi, Book 27, Hadith 33 (In-Book) ⓘ
Abu Hurairah narrated that the Messenger of Allah said: : "The Muslim is the brother to the Muslim, he does not cheat him, lie to him, nor deceive him. All of the Muslim is unlawful to another Muslim: His Honor, his wealth, and his blood. At-taqwa is here. It is enough evil for a man that he belittle his brother Muslim."
حَدَّثَنَا عُبَيْدُ بْنُ أَسْبَاطِ بْنِ مُحَمَّدٍ الْقُرَشِيُّ، حَدَّثَنِي أَبِي، عَنْ هِشَامِ بْنِ سَعْدٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْمُسْلِمُ أَخُو الْمُسْلِمِ لاَ يَخُونُهُ وَلاَ يَكْذِبُهُ وَلاَ يَخْذُلُهُ كُلُّ الْمُسْلِمِ عَلَى الْمُسْلِمِ حَرَامٌ عِرْضُهُ وَمَالُهُ وَدَمُهُ التَّقْوَى هَا هُنَا بِحَسْبِ امْرِئٍ مِنَ الشَّرِّ أَنْ يَحْتَقِرَ أَخَاهُ الْمُسْلِمَ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ . وَفِي الْبَابِ عَنْ عَلِيٍّ وَأَبِي أَيُّوبَ .
