The ruling on one who remains on his religion after the sending of the Prophet

Question:
And it is not shirk (associating partners with Allah) that Allah informed you about. As for what turned you away from the patient ones: whoever was in the time of the Messenger of Allah (peace and blessings be upon him) among the Jews, or whoever did not change or alter, he is upon the truth. And if it is

Answer:
this is authentic: the ones to whom the Prophet (peace and blessings be upon him) was sent were not upon the true Judaism, nor upon the true Christianity, but rather they were all distorters and changers. As for individuals among them, there may be individuals among them who accepted the call of the Messenger (peace and blessings be upon him), entered into the religion of Allah the Exalted, and followed the Messenger (peace and blessings be upon him), because their religion commands them to do so. But as for one who remained upon Judaism and Christianity after the sending of the Messenger, he is among the people of the Fire, and he is a disbeliever, a disbeliever in Allah, and not a believer. And if he claims that he follows the religion of Moses or the religion of Jesus, that is a lie, because the religion of Moses and the religion of Jesus and the religion of all the messengers commands following Muhammad (peace and blessings be upon him). Whoever lies about this verse and says he is a messenger to the Arabs specifically, or to other than the Jews and Christians, is a disbeliever in Allah, in His angels, in all of them, in His messengers, in the Last Day, and in the divine decree, its good and its evil. Yes. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad.
