Not Dead but Alive

Do not say of those slain in Allah’s cause, ‘They are dead.’ Rather, they are alive, though you do not perceive it.

2:154And call not those who are slain in the way of Allah "dead." Nay, they are living, only ye perceive not.

3:169Think not of those, who are slain in the way of Allah, as dead. Nay, they are living. With their Lord they have provision.
