Surah 26. Ash-Shuara
Ayah 44 - 48
44فَأَلْقَوْا۟ حِبَالَهُمْ وَعِصِيَّهُمْ وَقَالُوا۟ بِعِزَّةِ فِرْعَوْنَ إِنَّا لَنَحْنُ ٱلْغَـٰلِبُونَ
45فَأَلْقَىٰ مُوسَىٰ عَصَاهُ فَإِذَا هِىَ تَلْقَفُ مَا يَأْفِكُونَ
46فَأُلْقِىَ ٱلسَّحَرَةُ سَـٰجِدِينَ
47قَالُوٓا۟ ءَامَنَّا بِرَبِّ ٱلْعَـٰلَمِينَ
48رَبِّ مُوسَىٰ وَهَـٰرُونَ
[44-48] They forthwith cast down their cords and staffs and said. "By Pharaoh's honor, we shall surely win"36 Then Moses cast down his staff, and lo! It started devouring up their false devices. At this, all the magicians fell down in prostration, and cried out, "We have believed in the Lord of all creation the Lord of Moses and Aaron!"37
36As soon as they cast down their cords and staffs, these started moving like so many snakes- towards Moses. This has been described in greater detail at other places in the Qur'an. According to Al-A`raf: 116: "When they threw down their devices, they bewitched the eyes of the people and terrified their hearts: for they had indeed produced a great magic." And according to Ta Ha: 66, 67: "Suddenly it so appeared to Moses that their cords and staffs were running about by the power of their magic, and Moses' heart was filled with fear."
37This was not merely an acknowledgment of their defeat at the hands of Moses as though he was a greater magician, but their falling prostrate in submission to Allah, Lord of the universe, was an open declaration before thousands of Egyptians that what Moses had brought about was no magic at all, but a manifestation of the powers of Allah, Almighty.
