What is the meaning of the word (al-mu'addah) in the hadith (the one who buries [a child] alive and the one buried alive are in the Fire)?

The questioner : .

The Shaykh: Is it clear to you or not? That is, there is an implied element here that is not explicitly mentioned, but it is known by inference. [The hadith says] "the one who buries [a child] alive and the one buried alive are in the Fire," or "the one who buries [a child] alive and the one for whom the child was buried alive are in the Fire." There is no difficulty regarding the one who buries [a child] alive being in the Fire, because she is an adult and accountable. As for the child who was buried alive, the small infant, how can she be in the Fire? First: no bearer of a burden will bear the burden of another. Second: the pen is lifted from the child until he reaches puberty. This child who was buried alive knows nothing and understands nothing, so how can she be judged to be in the Fire? The answer is that the one intended is not the child who was buried alive in herself, but rather the one for whom the child was buried alive. Whether it is the father, or the mother, or both together, if they conspired and agreed to bury their daughter alive, then both of them are in the Fire. As for the child who was buried alive herself, she is not judged to be in Paradise or in the Fire. So the one who buries [a child] alive and the one for whom the child was buried alive, meaning the husband, are in the Fire. The one who buries [a child] alive is explicitly stated to be the mother because the word is feminine. As for the father, he is not explicitly mentioned in the hadith, but he is mentioned implicitly, because the phrase "and the one buried alive" cannot be taken at the literal level of the text, because the Shari'ah is decisive in its indication that the small child who has not reached the age of accountability is not accountable and is not held responsible, so he is not judged to be in the Fire. Therefore, the interpretation of the hadith, Yes.
