Good Manners and Form (Al-Adab)

Bukhari :: Book 8 :: Volume 73 :: Hadith 171

Narrated 'Aisha:

Hassan bin Thabit asked the permission of Allah's Apostle to lampoon the pagans (in verse). Allah's Apostle said, "What about my fore-fathers (ancestry)?' Hassan said (to the Prophet) "I will take you out of them as a hair is taken out of dough."

Narrated Hisham bin 'Urwa that his father said, "I called Hassan with bad names in front of 'Aisha." She said, "Don't call him with bad names because he used to defend Allah's Apostle (against the pagans)."
