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

وَقالوا مَهما تَأتِنا بِهِ مِن ءايَةٍ لِتَسحَرَنا بِها فَما نَحنُ لَكَ بِمُؤمِنينَ

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.
