Quran 67:30 — Kingship (Al-Mulk)

قُل أَرَءَيتُم إِن أَصبَحَ ماؤُكُم غَورًا فَمَن يَأتيكُم بِماءٍ مَعينٍ

Say, "What if your water sinks away, who will provide you with pure water?"

[67:29] Say, "He is the Most Gracious; we believe in Him, and we trust in Him. You will surely find out who is really far astray."
