Musnad Ahmad 6484 — Musnad of Abdullah ibn Amr ibn al-As

It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that I saw the Noble Prophet (peace and blessings be upon him) standing on his mount in the plain of Mina. Meanwhile, a man came and said, "O Messenger of Allah! I thought that shaving the head comes before sacrifice, so I had my head shaved before offering the sacrifice." The Noble Prophet (peace and blessings be upon him) said, "Go and offer the sacrifice, there is no harm." Another man came and said, "O Messenger of Allah! I thought that sacrifice comes before stoning, so I offered the sacrifice before stoning." The Noble Prophet (peace and blessings be upon him) said, "Now go and perform the stoning, there is no harm." On that day, for every question of this nature that was asked to the Noble Prophet (peace and blessings be upon him), he replied, "Now do it, there is no harm."
