Sahih Bukhari Volume 6, Book 60, Hadith Number 279.

Narrated By Masruq : ‘Aisha said that Hassan bin Thabit came and asked permission to visit her. I said, “How do you permit such a person?” She said, “Hasn’t he received a severely penalty?” (Sufyan, the sub narrator, said: She meant the loss of his sight.) Thereupon Hassan said the following poetic verse:

“A chaste pious woman who arouses no suspicion. She never talks about chaste heedless women behind their backs.’ On that she said, “But you are not so.”
