﴿ وَقَالُوا۟ مَهْمَا تَأْتِنَا بِهِۦ مِنْ ءَايَةٍۢ لِّتَسْحَرَنَا بِهَا فَمَا نَحْنُ لَكَ بِمُؤْمِنِينَ ﴾

“And they said [unto Moses]: "Whatever sign thou mayest produce before us in order to cast a spell upon us thereby, we shall not believe thee!"”

(And they said:) O Moses, whenever and (Whatever portent) sign (thou bringest wherewith to bewitch us) to dazzle our eyes with, (we shall not put faith in thee) we shall not believe in the message, and so Moses (pbuh) prayed against them.
