It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When you have given your family their fill of milk in the evening, then avoid the carrion that Allah has forbidden."
Abu Abdullah al-Halimi (may Allah have mercy on him) writes in his book that there is no harm in eating permissible food. If in the morning one finds something that suffices his needs until the evening, and in the evening eats what he left in the morning, there is no harm; (likewise) if he mixes in vegetables or adds something else. This is not the case with carrion; rather, he may eat of carrion only the amount that saves his life, and should not eat it the way lawful foods are eaten.
