On multiple levels the Arab Muslims can be shown to have immigrated into Israel in several waves.
Care to show me?
No problem, and to save time I'll quote Wiki a bit but if you have trouble with it I'm sure I can find many other sources for the information.

The
Islamization of Palestine occurred as a result of the
Islamic conquest in 640. It was a long process that included immigration of Muslim Arabs, as well as other Muslims, from other regions, as well as conversion to
Islam by some of the indigenous
Christian,
Samaritan and
Jewish population of the area. Islam did not become the majority religion of Palestine until at least the 9th century and possibly even as late as the
Mamluk era (1250–1516)

Thus we have the first wave of Arab Muslim immigrants.
Lets look at another source just to make sure we can agree
Feel free to vet Mr Parks

According to the historian
James William Parkes, during the 1st century after the Arab conquest (640–740), the caliph and governors of Syria and the Holy Land ruled entirely over Christian and Jewish subjects. He further states that apart from the
Bedouin in the earliest days, the only Arabs west of the Jordan were the garrisons.[5]

OK so now lets look at how many Muslims were actually in Jerusalem in the 1800s
Not sure this graph will paste but I'll give it a shot.
Nope
Ugh, OK I'll write out a few years showing just how few Muslims were in jerusalem

So now lets look at the what the rest of palestine looked like. Thing to remember is that we don't really know what the area of palestine was durring the Ottoman times because there was no area specifically called palestine on Ottoman maps. Instead we have a number of provinces. Gaza, Acre and Lebanon, all in southern Syria. So unless we know what area the various sources are counting its a little difficult to compare numbers. But lets give it a shot anyway
In the graph offered on WIKI we have some specifics but they clearly will blur the issue given that these numbers include Jordan, and doesn't include internal movements.

Jordan and the

Mandatory Palestine.

Although this link does describe large numbers of Arabs immigrating into the above defined area.

In the above graph you can see two waves of Arab immigration. One pre 1915 and one in the Zionist period matching nearly exactly the growth in the Judaic population.
Lets take a look at the "Harvard Israel Review"

From the period of the Crusades to the beginning of modern times, the population of Palestine remained at a near constant level.2This apparent stability is significant, as populations naturally tend to increase over time. It is estimated that there were 205,000 people living in Palestine in the mid 1500s.3By 1800, the population had only grown to 275,000, reflecting about a thousandth of a percent of average growth a year.4By 1890, still before any significant Jewish immigration, the population had made a slightly larger jump, to 532,000.5But even with this increase, the nineteenth century growth rate was still a small 0.7% per year.6By comparison, in the 1940s the Muslim growth rate in the Middle East was closer to 3.07%.7
A number of factors account for this dramatic underpopulation, one of which is environmental. Many people fled the area as early as the fourteenth century as a result of the Black Plague.

Soon afterwards, during World War I, the Ottomans tried to muster troops from the region, prompting many of the upper classes to flee. It appears that the war prompted a massive flight, immediately followed by a huge influx. According to contemporary surveys, the Arab population declined by 35,000 during the years 1915 to 1919. While many Arabs may have fled to escape the draft, others were expelled by force. To defend against the British, the Ottomans, still nominally in control, expelled both Jews and Arabs from cities across the coast on the assumption that their nationalistic intentions could lead them to sympathize with the British invaders. This effort was massive: twenty-eight thousand Arabs were forced out of Gaza alone.21By 1922, however, just three years later, the Arab population had increased by 80,000 above the 1919 level.22

After years of relative stagnation, the few decades leading up to 1948 saw significant growth in both Arab and Jewish populations. Had the Arab population remained at its pre-WWI growth rate (0.8%) after 1922, one would have expected a population of approximately 785,000 by 1947. But there were in fact between 1.2 and 1.3 million Arabs in all of Palestine by 1947.26What could have caused this sudden burst?
To investigate possible causes, it is important to examine where in the country the growth took place. Non-Jewish population growth rates were highest within modern-day sovereign Israel and in the West Bank and Gaza Strip regions. These rates cannot be explained by higher birth rates alone.
One major factor accounting for the unexpected growth was the potential for upward mobility that existed in the western cities. The wages of western cities were more attractive, no doubt bringing many people from surrounding areas. Port cities also offered greater employment opportunities, which helps explain the fact that there was a dramatic influx into Haifa and Jaffa relative to cities like Beit-Shean and Jerusalem.

That link is endlessly entertaining but the question of where all these Arabs came from is pretty well defined.
We know they were largely immigrants given the historically low pop growth rates. And we know the time frame of their arrival. We can also know that the Arab pop growth somehow miraculously matched the Judaic pop growth ( coincidence ? )
So the only conclusion can be that we have two distinct waves of Arab immigration. One in the Arab conquest period and another in the late Zionist period.
Ergo the Arabs cannot be the indigenous people of Judea
Case closed ;--)
