Ash-Shama'il Al-Muhammadiyah, Book 48, Hadith 350 (In-Book) ⓘ

'Aayeshah Radiyallahu 'Anha reports. "A person asked permission to present himself before Rasulullah Sallallahu 'Alayhi Wasallam while I was with him. Rasulullah Sallallahu 'Alayhi Wasallam said: 'What a bad person is he among his community'. After saying this, he gave him permission to enter. After the person entered, he spoke very softly to him. When the person left I said: 'O Rasulullah, you said what you said before he entered, then you spoke so softly to him,. Rasulullah Sallallahu 'Alayhi Wasallam said: 'O 'Aayeshah, the worst person is that who stops speaking to one because of his indecency'".

حَدَّثَنَا ابْنُ أَبِي عُمَرَ، قَالَ‏:‏ حَدَّثَنَا سُفْيَانُ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتِ‏:‏ اسْتَأْذَنَ رَجُلٌ عَلَى رَسُولِ اللهِ صلى الله عليه وسلم، وَأَنَا عِنْدَهُ، فَقَالَ‏:‏ بِئْسَ ابْنُ الْعَشِيرَةِ أَوْ أَخُو الْعَشِيرَةِ، ثُمَّ أَذِنَ لَهُ، فَأَلانَ لَهُ الْقَوْلَ، فَلَمَّا خَرَجَ، قُلْتُ‏:‏ يَا رَسُولَ اللهِ، قُلْتَ مَا قُلْتَ ثُمَّ أَلَنْتَ لَهُ الْقَوْلَ‏؟‏ فَقَالَ‏:‏ يَا عَائِشَةُ، إِنَّ مِنْ شَرِّ النَّاسِ مَنْ تَرَكَهُ النَّاسُ أَوْ وَدَعَهُ النَّاسُ اتِّقَاءَ فُحْشِهِ‏.‏
