وَإِنَّهُ سَيَأْتي عَلَيْكُمْ مِنْ بَعْدِي زَمَانٌ لَيْسَ...
The holders of the book will throw it away and its memorisers would forget it. In these days the Qur'an and its people will be exiled and expelled. They will be companions keeping together on one path, but no one will offer them asylum. Consequently at this time the Qur'an and its people will be among the people but not among them, will be with them but not with them, because misguidance cannot accord with guidance even though they may be together.
The people will have united on division and will therefore have cut away from the community, as though they were the leaders of the Qur'an and not the Qur'an their leader. Nothing of it will be left with them except its name, and they will know nothing save its writing and its words. Before that, they will inflict hardships on the virtuous, naming the latter's truthful views about Allah false allegations, and enforcing for virtues the punishment of the vice.
Those before you passed away because of the lengthening of their desires and the forgetting of their death, till that promised event befell them about which excuses are turned down, repentance is denied and punishment and retribution is inflicted.
