Good question. So I was stating the different opinions scholars have and this is one opinion. This does not contradict the verse that says Allah protects the Qur’an. In fact it confirms it. Allah has promised to protect the Qur’an, and one way by which he protected it is that he put those verses in a place that he know the Umayyads would not change. So indeed Allah protected the Qur’an. The way the Qur’an is organized and structured helped ensure that it would be protected.
