Quran 7:159 — The Purgatory (Al-A'araf)

Among the followers of Moses there are those who guide in accordance with the truth, and the truth renders them righteous.

[7:158] Say, "O people, I am GOD's messenger to all of you. To Him belongs the sovereignty of the heavens and the earth. There is no god except He. He controls life and death." Therefore, you shall believe in GOD and His messenger, the gentile prophet, who believes in GOD and His words. Follow him, that you may be guided.

[7:160] We divided them into twelve tribal communities, and we inspired Moses when his people asked him for water: "Strike the rock with your staff," whereupon twelve springs gushed out therefrom. Thus, each community knew its water. And we shaded them with clouds, and sent down to them manna and quails: "Eat from the good things we provided for you." It is not us that they wronged; it is they who wronged their own souls.
