Sahih Muslim Book 45, Hadith 95
This hadith has been reported on the authority of Ibn Munkadir with the same chain of transmitters but with a slight variation of wording.
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: Allah's Messenger, 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.
He who is deprived of tenderly feelings is in fact deprived of good.
