Surah Al-Mulk opens by placing all dominion in Allah's hand and names the purpose of life plainly: He created death and life to test which of us is best in deed. The Prophet ﷺ taught that it protects the one who recites it each night.
“Blessed is He in whose hand is dominion, and He is over all things competent - [He] who created death and life to test you [as to] which of you is best in deed...”— 67:1-2 (Saheeh International)
