1Sahil B = ""And while it is true that after a few years, Muhammad both changed the qiblah from Jerusalem to Mecca, and set the annual fast at Ramadan (the month in which the Quran was first revealed) instead of Yom Kippur, these decisions should not be interpreted as “a break with the Jews,” but as the maturing of Islam into its own independent religion. Despite the changes, Muhammad continued to encourage his followers to fast on Yom Kippur, and he never ceased to venerate Jerusalem as a holy city; indeed, after Mecca and Medina, Jerusalem is the most sacred city in the whole of the Muslim world. Moreover, the Prophet maintained most of the dietary, purity, and marriage restrictions he had adopted from the Jews. And until the day he died, Muhammad continued to engage in peaceful discourse—not theological debate —with the Jewish communities of Arabia, just as the Quran had commanded him to do: “Do not argue with the People of the Book—apart from those individuals who act unjustly toward you—unless it is in a fair way” (29:46). Muhammad’s example must have had a lasting effect on his early followers: as Nabia Abbott has shown, throughout the first two centuries of Islam, Muslims regularly read the Torah alongside the Quran."-No god but God, Reza Aslan "
