Surah 69. Al-Haqqah

7The illusion is to the Deluge of the Prophet Noah, in which a whole nation was drowned because of this very crime, and only those people were saved, who had listened to and obeyed the Messenger of Allah.

8"We boarded you...", because the whole human race that exists today has descended from the people who were boarded in the Ark thousands of years ago and thus saved from the Deluge. It means: "You exist in the world today because in that Deluge Allah had caused only the infidels to be drowned and had saved the believers.

9"The retaining ears,..": the ears which may hear it consciously and take it in. Although the word ear has been used, it implies the hearers who may hear the event and always remember it, take heed from it, and may never forget what dreadful fate the deniers of the Hereafter and the disbelievers of the Messenger of God would ultimately suffer.
