Early Muslims read Islam’s victories as proof that Judaism and Christianity were superseded religions

Evidence

But first, in this chapter, I explore what it looked like to the first generations of Muslims. … In the first chapter I examine seventh-century Christian conceptions of divine history and religious other; in this, we will examine the development of Muslim doctrines concerning theodicy and the religious other in the Koran, the Hadîth, and other key early Muslim texts. We will see how, for many early Muslims, the rise of Islam and its tremendous successes against Christians were proof of God’s favor: God allowed a small and pure band of his devotees to subdue two large and powerful but decadent empires. Judaism and Christianity were corrupt, superseded versions of the true religion, Islam; their adherents were to be tolerated, but were not to be considered equal to Muslims. — John V. Tolan, Saracens, 171
