Sahih Bukhari | Volume 5 | Hadith Number 466
Narrated by Hisham's father
I started abusing Hassan in front of 'Aisha. She said, "Do not abuse him as he used to defend Allah's Apostle (against the infidels). 'Aisha added, "Once Hassan took the permission from the Prophet to say poetic verses against the infidels. On that the Prophet said, 'How will you exclude my forefathers (from that)? Hassan replied, 'I will take you out of them as one takes a hair out of the dough." Hisham's father added, "I abused Hassan as he was one of those who spoke against 'Aisha."
