Surah Ash-Shu'ara, verse 48

فَأُلْقِىَ ٱلسَّحَرَةُ سَـٰجِدِينَ ﴿٤٦﴾

So the magicians fell down in prostration [to Allāh].

قَالُوٓا۟ ءَامَنَّا بِرَبِّ ٱلْعَـٰلَمِينَ ﴿٤٧﴾

They said, "We have believed in the Lord of the worlds,

قَالَ ءَامَنتُمْ لَهُۥ قَبْلَ أَنْ ءَاذَنَ لَكُمْ ۖ إِنَّهُۥ لَكَبِيرُكُمُ ٱلَّذِى عَلَّمَكُمُ ٱلسِّحْرَ فَلَسَوْفَ تَعْلَمُونَ ۚ لَأُقَطِّعَنَّ أَيْدِيَكُمْ وَأَرْجُلَكُم مِّنْ خِلَـٰفٍۢ وَلَأُصَلِّبَنَّكُمْ أَجْمَعِينَ ﴿٤٩﴾

[Pharaoh] said, "You believed him [i.e., Moses] before I gave you permission. Indeed, he is your leader who has taught you magic, but you are going to know. I will surely cut off your hands and your feet on opposite sides, and I will surely crucify you all."

قَالُوا۟ لَا ضَيْرَ ۖ إِنَّآ إِلَىٰ رَبِّنَا مُنقَلِبُونَ ﴿٥٠﴾

They said, "No harm. Indeed, to our Lord we will return.
