Will angels help the Muslim who did not memorize the Quran in this life to memorize it in his grave?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

There is no basis for this piece of information and what happens in the grave is a matter of the unseen that we cannot know, except via a text of the Quran or the Sunnah. In fact, there is no text to support this issue. Therefore, a Muslim must be keen to memorize the Quran in this worldly life and abide by its orders and avoid its prohibitions. It should be known that man will have nothing but the reward from the deeds he strives for, and that the Hereafter is a world of recompense, not a world for doing deeds.

Allaah Knows best.
