Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا صَدَقَةُ بْنُ الْفَضْلِ، أَخْبَرَنَا ابْنُ عُيَيْنَةَ، سَمِعْتُ ابْنَ الْمُنْكَدِرِ، سَمِعَ عُرْوَةَ بْنَ الزُّبَيْرِ، أَنَّ عَائِشَةَ ـ رضى الله عنها ـ أَخْبَرَتْهُ قَالَتِ، اسْتَأْذَنَ رَجُلٌ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ " ائْذَنُوا لَهُ بِئْسَ، أَخُو الْعَشِيرَةِ أَوِ ابْنُ الْعَشِيرَةِ ". فَلَمَّا دَخَلَ أَلاَنَ لَهُ الْكَلاَمَ قُلْتُ يَا رَسُولَ اللَّهِ قُلْتَ الَّذِي قُلْتَ، ثُمَّ أَلَنْتَ لَهُ الْكَلاَمَ قَالَ " أَىْ عَائِشَةُ، إِنَّ شَرَّ النَّاسِ مَنْ تَرَكَهُ النَّاسُ ـ أَوْ وَدَعَهُ النَّاسُ ـ اتِّقَاءَ فُحْشِهِ ".
A man asked permission to enter upon Allah's Messenger (ﷺ). The Prophet (ﷺ) said, "Admit him. What an evil brother of his people or a son of his people." But when the man entered, the Prophet (ﷺ) spoke to him in a very polite manner. (And when that person left) I said, "O Allah's Messenger (ﷺ)! You had said what you had said, yet you spoke to him in a very polite manner?" The Prophet (ﷺ) said, "O `Aisha! The worst people are those whom the people desert or leave in order to save themselves from their dirty language or from their transgression."
