{ And indeed whether you are killed for the sake of Allah, or die, surely forgiveness from Allah and mercy are better than what those people accumulate } Al ‘Imran 157

{ And indeed whether you are killed for the sake of Allah, or die, surely forgiveness from Allah and mercy are better than what they accumulate } : this indicates that killing for the sake of Allah, as well as death, are a way to gain the mercy of Allah, His forgiveness, and His good pleasure, and this is better than remaining in this world.
