im glad you ask me specifically, so i can know that i will have something to do when i check up on these threads. i will give a reply, but you will most probably ask me how i know, and the answer is from the quran
from the descent of adam to this world, up until the death of the prophet muhammad, there has always been prophets sent to humans. adam was the first prophet obviously, then as society became less thinking of allah, he sent another prophet to them to wake them up again. this has been happening since adam came to earth, but the quran only gives the names of 25 specific ones. noah was a prophet, abraham, the builder of the oldest place of worship, was a prophet, jesus and muhammad are from ibrahims descent, and they were prophets. there are like i said 25 names in the quran, but only muhammad, jesus, david, and another prophet that came with a message. the other prophets came to place the people back on track, and to follow the book sent down latest. you might ask "who came to put christians back on track?" the answer is that the prophets werte sent down in pairs, and muhammad and jesus were the last pair, so no one came between them, and no one will come after them.
also the prophets came to specific people and tribes, all except for muhammad, which came for all mankind.
