4. And when the Graves are turned upside down

Notes (Tafseer)

6001. This item is not mentioned in lxxxi. 1-14. Here it is introduced to show that the whole order of things will be so reversed that even Death will not be Death. We think there is tranquillity in Death: but there will be no tranquillity. Literally, and figuratively, Death will be the beginning of a new Life. What we think to be Death will bring forth Life.
