SURAH AL-ARAF (THE HEIGHTS): 154-155

[7:154]
When the fury of Musa calmed down, he picked up the Tablets, and in its contents there was guidance, and mercy for those who are fearful before their Lord.
[7:155]

And Musa selected seventy men from his people for Our appointment. Later when the earthquake seized them, he said, "My Lord, had it been Your will, You could have destroyed them earlier, and me too. Would You destroy us for what the foolish among them have done? It is nothing but a trial from You, wherewith you let go astray whom You will, and give guidance to whom You will. You are our protector, so forgive us, and have mercy on us, and You are the best among those who forgive."
