Quran 7:131 — The Purgatory (Al-A'araf)

When good omens came their way, they said, "We have deserved this," but when a hardship afflicted them, they blamed Moses and those with him. In fact, their omens are decided only by GOD, but most of them do not know.

[7:130] We then afflicted Pharaoh's people with drought, and shortage of crops, that they may take heed.

[7:132] They said, "No matter what kind of sign you show us, to dupe us with your magic, we will not believe."
