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 عليه السلام and a female servant of the Imam عليه السلام. The female servant, however, vomited the poison, but in the case of al-Hassan عليه السلام the poison remained in his digestive system and caused swelling that killed him.”
