Are the two allegations that accuse Muslims of not having changed the Qibla until the reign of Abd al-Malik ibn Marwan, and of fabricating the tribes of Banu al-Nadir, Qaynuqa, and Qurayza, correct?

There is no meaning to the شبهات (doubts/misconceptions) surrounding the change of the Qibla and the presence of Jews in the Arabian Peninsula. The Qur'an commanded the change of the Qibla from Jerusalem to the Kaaba. The claim that the verses were interpolated into the Qur'an during the time of Abd al-Malik is a slander and a display of historical ignorance, for the Qur'an is preserved by the preservation of Allah. Similarly, the absence of mention of the Jews of Banu Qurayza, An-Nadir, and Qaynuqa' in Jewish references does not diminish the established fact of their mention in the Qur'an, the continuously transmitted Sunnah, and Islamic history. Some researchers attribute this to the weak communication between the Jews of Sham (Syria) at that time. These matters are definitively established, and their denial is clear obstinacy. One must turn away from these absurdities and adhere to the Qur'an and Sunnah.
