Bayhaqi's Dala'il — the glorification of the pebbles

دلائل النبوة للبيهيقي — تسبيح الحصيات

Abu Dharr reports that the Prophet ﷺ sat alone; Abu Bakr sat at his right, then Umar, then Uthman, while seven or nine pebbles lay before him. He took them in his palm and they glorified God until their humming was heard like bees; he then placed them in Abu Bakr's hand and they glorified again, then in Umar's, then in Uthman's, and said: this is the succession of prophethood. The margin notes the report reaches Abu Dharr through al-Rabdha and has isnad criticism, yet it remains among the most famous proofs cited in the dalail literature.
