4ـ وَعَنْهُ عَنْ أَحْمَدَ عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ الْخَزَّازِ عَنْ سُلَيْمَانَ بْنِ خَالِدٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ مَا مِنْ أَحَدٍ يَمُوتُ مِنَ الْمُؤْمِنِينَ أَحَبَّ إِلَى إِبْلِيسَ مِنْ مَوْتِ فَقِيهٍ.
4. From him (Muhammad ibn Yahya) from Ahmad from ibn Mahbub from abu Ayyub al-Khazzaz from Sulayman ibn Khalid that Abu ‘Abdillah (as) said, "Of the deaths of the believers that Satan loves most, is the death of a Faqih (a knowledgable person of islamic laws)."
