Sayyiduna Uqbah bin Amir (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) gave me goats (for sacrifice) to distribute among the companions, so I distributed them. Among them, one kid less than a year old remained. I mentioned this to the Messenger of Allah (peace and blessings be upon him), so he said: "Sacrifice this one as well." Imam Darimi (may Allah have mercy on him) said: «عتود» refers to a kid goat.
