Chapter 115 | The Birth of al-Hassan ibn Ali
3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنْ سَيْفِ بْنِ عَمِيرَةَ عَنْ أَبِي بَكْرٍ الْحَضْرَمِيِّ قَالَ إِنَّ جَعْدَةَ بِنْتَ أَشْعَثَ بْنِ قَيْسٍ الْكِنْدِيِّ سَمَّتِ الْحَسَنَ بْنَ عَلِيٍّ وَسَمَّتْ مَوْلاةً لَهُ فَأَمَّا مَوْلاتُهُ فَقَاءَتِ السَّمَّ وَأَمَّا الْحَسَنُ فَاسْتَمْسَكَ فِي بَطْنِهِ ثُمَّ انْتَفَطَ بِهِ فَمَاتَ.
3. A number of our people have narrated from Ahmad ibn Muhammad from Ali ibn al-Nu‘man from Sayf ibn ‘Amira from Abu Bakr al-Hadrami who has said the following: "Ja'da bint al-Ash‘ath ibn Qays al-Kindi poisoned al-Hassan ibn Ali and a female servant of the Imam . The female servant, however, vomited the poison, but in the case of al-Hassan the poison remained in his digestive system and caused swelling that killed him.”
