If Allah willed, He could take away the Qur'an

Allah mentions the blessing and great bounty that He has bestowed upon His servant and Messenger Muhammad by revealing to Him the Noble Qur'an to which falsehood cannot come, from before it or behind it, (it is) sent down by the All-Wise, Worthy of all praise. Ibn Mas`ud said, "A red wind will come to the people, meaning at the end of time, from the direction of Syria, and there will be nothing left in a man's Mushaf (copy of the Qur'an) or in his heart, not even one Ayah." Then Ibn Mas`ud recited:

وَلَئِن شِئْنَا لَنَذْهَبَنَّ بِالَّذِى أَوْحَيْنَا إِلَيْكَ

The last verse: وَلَقَدْ صَرَّ‌فْنَا (And surely We have explained - 89) tells us that the Holy Qur’ an stands out as a miracle so clear that it leaves no room for any question and doubt. Still, what is happening is that people do not thank Allah for His blessings, do not even recognize the real worth of the blessing of the Qur'an and keep wandering around in error.
