Sahih al-Bukhari 3531
Narrated `Aisha:
Once Hassan bin Thabit asked the permission of the Prophet (ﷺ) to lampoon (i.e. compose satirical poetry 
defaming) the infidels. The Prophet (ﷺ) said, "What about the fact that I have common descent with 
them?" Hassan replied, "I shall take you out of them as a hair is taken out of dough." 
Narrated `Urwa: I started abusing Hassan in front of `Aisha, whereupon she said. "Don't abuse him, 
for he used to defend the Prophet (with his poetry).
حَدَّثَنِي عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدَةُ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتِ اسْتَأْذَنَ حَسَّانُ النَّبِيَّ صلى الله عليه وسلم فِي هِجَاءِ الْمُشْرِكِينَ، قَالَ ‏
"‏ كَيْفَ بِنَسَبِي ‏"‏‏.‏ فَقَالَ حَسَّانُ لأَسُلَّنَّكَ مِنْهُمْ كَمَا تُسَلُّ الشَّعَرَةُ مِنَ الْعَجِينِ‏.‏ وَعَنْ أَبِيهِ قَالَ ذَهَبْتُ أَسُبُّ حَسَّانَ عِنْدَ عَائِشَةَ فَقَالَتْ لاَ تَسُبُّهُ فَإِنَّهُ كَانَ يُنَافِحُ عَنِ النَّبِيِّ صلى الله عليه وسلم‏.‏
