Musannaf Ibn Abi Shaybah 31631 — The supplication when stoning

Mughirah said: "I asked Ibrahim: 'When I throw pebbles at the Shaytan, what supplication should I recite?' He said: 'Recite this supplication: O Allah, make this an accepted Hajj and forgive sins.'" Mughirah said: "I asked: 'Should I recite these words with each pebble?' He said: 'Yes, if you wish.'"
