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.

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)
