Yahya ibn Yahya narrated to us, saying: I recited to Malik, from Ibn Shihab, from 'Isa ibn Talhah ibn 'Ubayd Allah, from 'Abd Allah ibn 'Amr ibn al-'As, who said: The Messenger of Allah, peace and blessings be upon him, stood at Mina during the Farewell Pilgrimage for the people, and they were asking him. A man came and said: "O Messenger of Allah, I did not know, and I shaved my head before I sacrificed." He said: "Sacrifice, and there is no harm." Then another man came to him and said: "O Messenger of Allah, I did not know, and I sacrificed before I threw the stones." He said: "Throw the stones, and there is no harm." He said: And the Messenger of Allah, peace and blessings be upon him, was not asked about anything that was brought forward or delayed, except that he said: "Do it, and there is no harm."
