Bayhaqi's Dala'il — the opening of the chest in infancy

دلائل النبوة للبيهيقي — شق الصدر عند الحليمة

This edition's introduction weighs whether the infant chest-opening counts among the proofs of prophethood, quoting Ibn Hibban (d. 354 AH): it was a distinction granted to him above others and is of the miracles of prophethood, for when people's chests are opened at the heart's place and their hearts removed they die — while God who says 'Be, and it is' is not barred by what physicians of any age cannot do. The editor holds the maghazi tradition the reliable core, sets aside the embellishments in the report of Muhammad ibn Zakariya al-Ghallabi who was suspected of fabrication, and keeps the account on the strength of its fame among the traditionists.
