صحيح البخاري#6150Sahihحَدَّثَنَا مُحَمَّدٌ، حَدَّثَنَا عَبْدَةُ، أَخْبَرَنَا هِشَامُ بْنُ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتِ اسْتَأْذَنَ حَسَّانُ بْنُ ثَابِتٍ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي هِجَاءِ الْمُشْرِكِينَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " فَكَيْفَ بِنَسَبِي ". فَقَالَ حَسَّانُ لأَسُلَّنَّكَ مِنْهُمْ كَمَا تُسَلُّ الشَّعَرَةُ مِنَ الْعَجِينِ. وَعَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ قَالَ ذَهَبْتُ أَسُبُّ حَسَّانَ عِنْدَ عَائِشَةَ فَقَالَتْ لاَ تَسُبُّهُ فَإِنَّهُ كَانَ يُنَافِحُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم.
Narrated `Aisha:Hassan bin Thabit asked the permission of Allah's Messenger (ﷺ) 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 Messenger (ﷺ) (against the pagans)
