Chapter 18 | Intercession and Those who will come out of the Fire (of Hell)
فضالة عن ربعي عن الفضيل عن أبي جعفر عليه السلام قال: إن آخر من يخرج من النار لرجل يقال له: همام (هام) ينادى فيها عمرا: يا حنان يا منان.
6.Faḍālah narrated from Ribʿī, from al-Fuḍayl, from Abū Jaʿfar who said, “Verily the last one to come out of the Fire will be a man called Hammām, who will call out therein [continually] for a lifetime: ‘O Compassionate! O Munificent!’”
