No. There’s no “caste system” in Islam. No person is superior because of race, nationality, tribe, or wealth. The only measure of superiority is taqwā (piety / God-consciousness).
“Indeed, the most honorable of you in the sight of Allah is the most righteous (the one with the most taqwā).”
Qur'an, Surah Al-Hujurat (49:13)
