Say: “If the last Home, with Allah, be for you specially, and not for anyone else, then seek ye for death, if ye are sincere.”

This is a subtle, satirical reference to their excessive worldliness. Those who really care for the Hereafter neither set their hearts on earthly life, nor are they unduly frightened of death. The condition of the Jews was the reverse of this.
