"A man sought permission to enter upon the Messenger of Allah while I was with him, so he said: 'What an evil son of his tribe, or brother of his tribe.' Then he admitted him and spoke with him. When he left, I said: 'O Messenger of Allah! You said what you said about him. Then you talked politely with him?' He said: 'O 'Aishah! Indeed among the evilest of people are those whom the people avoid, or who the people leave, fearing his filthy speech.'"  

قَالَتِ اسْتَأْذَنَ رَجُلٌ عَلَى رَسُولِ اللَّهِ ﷺ وَأَنَا عِنْدَهُ فَقَالَ بِئْسَ ابْنُ الْعَشِيرَةِ أَوْ أَخُو الْعَشِيرَةِ ثُمَّ أَذِنَ لَهُ فَأَلاَنَ لَهُ الْقَوْلَ فَلَمَّا خَرَجَ قُلْتُ لَهُ يَا رَسُولَ اللَّهِ قُلْتَ لَهُ مَا قُلْتَ ثُمَّ أَلَنْتَ لَهُ الْقَوْلَ فَقَالَ يَا عَائِشَةُ إِنَّ مِنْ شَرِّ النَّاسِ مَنْ تَرَكَهُ النَّاسُ أَوْ وَدَعَهُ النَّاسُ اتِّقَاءَ فُحْشِهِ  

Grant him permission. (and also added: ) He is a bad son of his tribe or he is a bad person of his tribe. When he came in he used kind words for him. 'A'isha reported that she said: Messenger of Allah, you said about him what you had to say and then you treated him with kindness. He said: A'isha, verily in the eye of Allah, worst amongst the person in rank on the Day of Resurrection is one whom the people abandon or desert out of the fear of indecency. (Using translation from Muslim 2591a)   

أَنَّهُ سَمِعَ عَائِشَةَ تَقُولُ اسْتَأْذَنَ عَلَى رَسُولِ اللَّهِ ﷺ رَجُلٌ فَقَالَ «ائْذَنِي لَهُ فَبِئْسَ ابْنُ الْعَشِيرَةِ أَوْ بِئْسَ رَجُلُ الْعَشِيرَةِ» فَلَمَّا دَخَلَ عَلَيْهِ أَلَانَ لَهُ الْقَوْلَ فَلَمَّا خَرَجَ قُلْتُ أَيْ رَسُولَ اللَّهِ قُلْتَ لَهُ الَّذِي قُلْتَ فَلَمَّا دَخَلَ أَلَنْتَ لَهُ الْقَوْلَ قَالَ ﷺ «أَيْ عَائِشَةُ إِنَّ شَرَّ النَّاسِ مَنْزِلَةً عِنْدَ اللَّهِ مَنْ تَرَكَهُ النَّاسُ أَوْ وَدَعَهُ النَّاسُ اتِّقَاءَ شَرِّهِ»
