Yahya related to me from Malik from Yahya ibn Said from Abbad ibn
Tamin that one time Uwaymir ibn Ashqar sacrificed his animal before
the prayer on the morning of the Day of Sacrifice, and he mentioned
that the Messenger of Allah, may Allah bless him and grant him peace,
had ordered him to sacrifice another animal.
