Quran 2:154 — The Heifer (Al-Baqarah)

وَلا تَقولوا لِمَن يُقتَلُ فى سَبيلِ اللَّهِ أَموٰتٌ ۚ بَل أَحياءٌ وَلٰكِن لا تَشعُرونَ

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.
