Ahmad Isn't Muhammad (ﷺ)

In the Quran, there exists a verse that shows Jesus saying that there will be another Prophet to come after him, whose name is "Ahmad." Some people may think that this can't be referring to Prophet Muhammad, since his name isn't "Ahmad":

In reply to that, "Ahmad (أحمد)" is a name derived from an adjective, not a verb; the structure of this adjective in grammar gives the meaning of preferableness and praisedness, and therefore the name "Ahmad" merely means "the one who praises his Lord the most." All prophets are praising Allah but our Prophet is the most one who praises Allah. On other note, the name "Muhammad (محمد)" is derived from an adjective, as well, which gives the meaning of "being praised by others frequently and excessively." "Muhammad" as a name means "the one who is praised once over and over," thus the name "Muhammad" matches its meaning; of getting praised by others excessively.

Allah named the Prophet before he is named by others, which is one of the signs of his Prophethood as his name matched his status and character because he is praised in this life due to the guidance, wisdom, and knowledge that he obtained and benefited others with, and he is praised in the hereafter because of the intercession that he was honored with by Allah. Therefore the meaning of praising was used as suitable. He was never "Muhammad" (i.e., praised by others) until he was "Ahmad" (i.e., praising Allah a lot), and that's the reason why the name "Ahmad" comes before the name "Muhammad."

So from this detailed explanation, Jesus was predicting the coming of someone not by the actual name, but by the feature or characteristic of said person; much like a nickname, and this figure of speech is very common, even nowadays. For example, Abdul-Rahman is one of the greatest companions of the Prophet, yet he was nicknamed "Abū Hurayrah (أبو هريرة)," meaning "father of the kitten," because he had a habit of holding a little kitten with him wherever he went; his nickname was given based on a characteristic that he had. Another example would be from the Bible:

Here, Matthew 1:22-23 is quoting Isaiah 7:14 in order to show that this prophecy is fulfilled in Jesus, however, the prophecy says that the child will be called "Immanuel," yet the Christians would simply argue the same thing. Even though they're correct in that, the argument from the Muslim side remains stronger; nowhere in the Bible did Jesus state he was "Immanuel" or was ever particularly called by that name anywhere else, meanwhile, Prophet Muhammad had several names that he claimed for himself and "Ahmad" is actually one of them:
