"We divided them into twelve tribes or nations. We directed Moses by inspiration, when his [thirsty] people asked him for water: "Strike the rock with thy staff": out of it there gushed forth twelve springs: Each group knew its own place for water. We gave them the shade of clouds, and sent down to them manna and quails, [saying]: "Eat of the good things We have provided for you": [but they rebelled]; to Us they did no harm, but they harmed their own souls."— Yusuf Ali translation
