Aswad bin Qais narrates that it is reported from Sayyiduna Jundub (may Allah be pleased with him) that he was present with the Messenger of Allah (peace and blessings be upon him) on the occasion of Eid, and he stated that the Messenger of Allah (peace and blessings be upon him) first performed the Eid prayer, then delivered the sermon and said: Whoever has slaughtered an animal before the prayer, let him offer another sacrifice in its place, and whoever has not yet slaughtered, let him slaughter in the name of Allah Almighty.
