Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Hassan ibn Mahbub from Ali ibn al-Ri’ab from Abu ‘Ubayda al-Hadhdha’ that Abu Ja’far (al-Baqir) (as) said, “Whoever gives a fatwa (a religious verdict) to people without knowledge and guidance, the angels of mercy and the angels of punishment curse him.

The burden of those who act upon his fatwa will fall upon him." صحيح - Shaykh Baqir al-Behbudi (Sahih al-Kafi (1/5)) صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (1/137))
