Quran 7:132 — The Purgatory (Al-A'araf)

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

[7:131] 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.

[7:133] Consequently, we sent upon them the flood, the locusts, the lice, the frogs, and the blood—profound signs. But they maintained their arrogance. They were evil people.
