Al-Kāfi|Volume 7|Book 6|Chapter 4
2- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنِ ابْنِ رِئَابٍ عَنْ أَبِي عُبَيْدَةَ قَالَ قَالَ أَبُو جَعْفَرٍ (عَلَيْهِ السَّلام) مَنْ أَفْتَى النَّاسَ بِغَيْرِ عِلْمٍ وَلا هُدًى مِنَ اللهِ لَعَنَتْهُ مَلائِكَةُ الرَّحْمَةِ وَمَلائِكَةُ الْعَذَابِ وَلَحِقَهُ وِزْرُ مَنْ عَمِلَ بِفُتْيَاهُ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from ibn Ri’ab from abu ‘Ubaydah who has narrated the following: “Abu Ja’far عليه السلام, has said, ‘If one issues fatwas without knowledge and guidance from Allah, all angels, of mercy and angels of suffering condemn him and the sin of those who follow his fatwas will be attached to him.’”
