Mukhtasar Bukhari

Narrated from Sayyiduna Abdullah bin Amr bin Al-As (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) stayed in Mina for the people during the Farewell Pilgrimage. People would ask him questions about religious matters. Then a man came and said, "Unknowingly, I shaved my head before sacrificing (the animal)." So the Prophet (peace and blessings of Allah be upon him) said: "(Now) sacrifice (the animal), and there is no harm." Then another man came and said, "Unknowingly, I offered the sacrifice before stoning (the Jamarat)." So the Prophet (peace and blessings of Allah be upon him) said: "(Now) perform the stoning, and there is no harm." (Abdullah bin Amr (may Allah be pleased with them both) says that on that day) whatever was asked of the Prophet (peace and blessings of Allah be upon him) regarding the order of the rites of Hajj, whether it was done earlier or later, the Prophet (peace and blessings of Allah be upon him) said the same: "Do it now, and there is no harm."
