Surah Al-A'raf, ayah 132

وَقَالُواْ مَهۡمَا تَأۡتِنَا بِهِۦ مِنۡ ءَايَةٖ لِّتَسۡحَرَنَا بِهَا فَمَا نَحۡنُ لَكَ بِمُؤۡمِنِينَ ١٣٢

Waqālū mahmā ta'tinā bihī min āyatil litasharanā bihā famā nahnu laka bimu'minīn

And they said, "No matter what sign you bring us with which to bewitch us, we will not be believers in you."
