What is the validity of the claim by some that the Shari'ah of Moses and Jesus was not abrogated, but is the same Shari'ah of Muhammad (peace and blessings be upon him)?

Question:
He says: Honorable Shaykh, may Allah grant you success, some people claim that the Shari'ah of Moses and Jesus (peace be upon them) was not abrogated, but rather it is the same Shari'ah of Muhammad (peace and blessings be upon him).

Answer:
It was not abrogated in the sense that the religion of the prophets is one in tawhid (the oneness of Allah) and creed. As for the practical branches, these differ according to the nations. They are abrogated and are not Shari'ahs . Because the branch Shari'ahs differ according to the needs and circumstances of the nations. Yes. So the one who says this is ignorant, he has no knowledge, or he hears that their religion is one in creed and thinks that it is so even in the branches. Yes. It is obligatory for a person to learn and know the truth, and not to follow his own head and say what is in his mind without knowledge. Yes.
