Al-A'raf - 7:132

وَقَالُواْ مَهْمَا تَأْتِنَا بِهِ مِن آيَةٍ لِّتَسْحَرَنَا بِهَا فَمَا نَحْنُ لَكَ بِمُؤْمِنِينَ
[7:132]
And they said: Whatever sign you may bring to us to charm us with it-- we will not believe in you.
They said (to Moses): "Whatever be the Signs thou bringest, to work therewith thy sorcery on us, we shall never believe in thee.
And they said: Whatever portent thou bringest wherewith to bewitch us, we shall not put faith in thee.
