عن عائشة رضي الله عنها قالت: استأذن رجل على رسول الله صلى الله عليه وسلم وأنا عنده فقال بئس ابن العشيرة أو أخو العشيرة ثم أذن له فلما دخل ألان له القول فلما خرج قلت يا رسول الله قلت ما قلت ثم ألنت له القول فقال: يا عائشة إن من شر الناس من تركه الناس أو ودعه الناس اتقاء فحشه (الشمائل المحمدية للترمذي، الرقم: 333)

Hazrat Aa’ishah (radhiyallahu ‘anha) reports:

On one occasion, while I was present with Rasulullah (sallallahu ‘alaihi wasallam), a certain person sought permission to enter his noble presence. (Before the person entered the mubaarak presence of Rasulullah (sallallahu ‘alaihi wasallam)), Rasulullah (sallallahu ‘alaihi wasallam) remarked, “How evil is this person from the people of his tribe”. Rasulullah (sallallahu ‘alaihi wasallam) then permitted him to enter. When he entered, Rasulullah (sallallahu ‘alaihi wasallam) spoke to him in a polite and courteous manner. After he left, I asked Rasulullah (sallallahu ‘alaihi wasallam), “O Rasul of Allah (sallallahu ‘alaihi wasallam)! You mentioned to me (prior to his entry) that which you mentioned (regarding his condition), yet you thereafter spoke to him in a polite and courteous manner?” Rasulullah (sallallahu ‘alaihi wasallam) then replied, “O Aa’ishah (radhiyallahu ‘anha)! Indeed the worst person is he whom people avoid or disassociate with in order to save themselves from his evil.”
