Quran 2:154 — The Heifer (Al-Baqarah)

Do not say of those who are killed in the cause of GOD, "They are dead." They are alive at their Lord, but you do not perceive.

[2:153] O you who believe, seek help through steadfastness and the Contact Prayers (Salat). GOD is with those who steadfastly persevere.

[2:155] We will surely test you through some fear, hunger, and loss of money, lives, and crops. Give good news to the steadfast.
