ثُمَّ إِنَّكُم بَعْدَ ذَٰلِكَ لَمَيِّتُونَ

Then, after all this, you are to die - 23:15

The preceding three verses were about the creation of man and this verse and the one which follows is about the life to come. In this verse Allah says that after his creation man will spend a period of time in this world and then will meet his death from which there is no escape. Then He says that man will be raised on the Day of Resurrection
