Muwatta Malik, Book 47, Hadith 4 (USC-MSA) ⓘ

Yahya related to me from Malik that he had heard that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "A man asked permission to come in to see the Messenger of Allah, may Allah bless him and grant him peace. I was with him in the house and the Messenger of Allah, may Allah bless him and grant him peace, said, 'He is an evil member of his tribe.' Then the Messenger of Allah, may Allah bless him and grant him peace, gave him permission." A'isha continued, "It was not long before I heard the Messenger of Allah, may Allah bless him and grant him peace, laughing with him. When the man left, I said, 'Messenger of Allah, you said what you said about him, and then before long you were laughing with him.' The Messenger of Allah, may Allah bless him and grant him peace, replied, 'Among the most evil of people is the one whom people are cautious with because of his evil.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم أَنَّهَا قَالَتِ اسْتَأْذَنَ رَجُلٌ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَتْ عَائِشَةُ وَأَنَا مَعَهُ فِي الْبَيْتِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ بِئْسَ ابْنُ الْعَشِيرَةِ ‏"‏ ‏.‏ ثُمَّ أَذِنَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏.‏ قَالَتْ عَائِشَةُ فَلَمْ أَنْشَبْ أَنْ سَمِعْتُ ضَحِكَ رَسُولِ اللَّهِ صلى الله عليه وسلم مَعَهُ فَلَمَّا خَرَجَ الرَّجُلُ قُلْتُ يَا رَسُولَ اللَّهِ قُلْتَ فِيهِ مَا قُلْتَ ثُمَّ لَمْ تَنْشَبْ أَنْ ضَحِكْتَ مَعَهُ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّ مِنْ شَرِّ النَّاسِ مَنِ اتَّقَاهُ النَّاسُ لِشَرِّهِ ‏"‏ ‏.‏
