I started abusing Hassan in front of ʿAisha. She said, "Do not abuse him as he used to defend Allah's Apostle (against the infidels). ʿAisha added, "Once Hassan took the permission from the Prophet ﷺ to say poetic verses against the infidels. On that the Prophet ﷺ 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 ʿAisha."
عَنْ رَسُولِ اللَّهِ ﷺ وَقَالَتْ عَائِشَةُ اسْتَأْذَنَ النَّبِيَّ ﷺ فِي هِجَاءِ الْمُشْرِكِينَ قَالَ كَيْفَ بِنَسَبِي قَالَ لأَسُلَّنَّكَ مِنْهُمْ كَمَا تُسَلُّ الشَّعْرَةُ مِنَ الْعَجِينِ وَقَالَ مُحَمَّدٌ حَدَّثَنَا عُثْمَانُ بْنُ فَرْقَدٍ سَمِعْتُ هِشَامًا عَنْ أَبِيهِ قَالَ سَبَبْتُ حَسَّانَ وَكَانَ مِمَّنْ كَثَّرَ عَلَيْهَا
