Nazareth.

Nazareth (pronounced /ˈnæzərəθ/; Hebrew: נָצְרַת‎‎, Natzrat or Natzeret; Arabic: الناصرة‎ al-Nāṣira or al-Naseriyye) is the largest city in the North District of Israel. Known as "the Arab capital of Israel," the population is predominantly made up of Arab citizens of Israel.

"The Nazareth metropolis area has a population of approximately 210,000 of which over 125,000 (59%) are Israeli Arabs, and 85,000 are Israeli Jews (41%), making it the only urban area with over 50,000 residents in Israel where the majority of the population is Arabic.[68]"

.........nazareth is correct (overall probably jerusalem cause its the biggest)

despite being in israel, nazareth is home to more palestinians than jews

Jerusalem is Israel's biggest city, and it does have 209,000 Muslims according to Wikipedia, which counts as Israel's largest Muslim population by city.

Edit: Ignoring Jerusalem, which I would imagine donates mostly from the Eastern section, Nazareth seems to be the biggest with 66,300. It's at least the biggest Arab city, as in not cohabiting with the Jews.

Nazareth , It's the arab capital of Israel and the only city in Israel with a predominently arab population (59%)
