Al-A'raf 7:120

وَأَوْحَيْنَا إِلَىٰ مُوسَىٰ أَنْ أَلْقِ عَصَاكَ ۖ فَإِذَا هِيَ تَلْقَفُ مَا يَأْفِكُونَ

And We inspired to Moses, "Throw your staff," and at once it devoured what they were falsifying.

فَوَقَعَ الْحَقُّ وَبَطَلَ مَا كَانُوا يَعْمَلُونَ

So the truth was established, and abolished was what they were doing.

فَغُلِبُوا هُنَالِكَ وَانقَلَبُوا صَاغِرِينَ

And Pharaoh and his people were overcome right there and became debased.

قَالُوا آمَنَّا بِرَبِّ الْعَالَمِينَ

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

رَبِّ مُوسَىٰ وَهَارُونَ

The Lord of Moses and Aaron."

قَالَ فِرْعَوْنُ آمَنتُم بِهِ قَبْلَ أَنْ آذَنَ لَكُمْ ۖ إِنَّ هَـٰذَا لَمَكْرٌ مَّكَرْتُمُوهُ فِي الْمَدِينَةِ لِتُخْرِجُوا مِنْهَا أَهْلَهَا ۖ فَسَوْفَ تَعْلَمُونَ

Said Pharaoh, "You believed in him before I gave you permission. Indeed, this is a conspiracy which you conspired in the city to expel therefrom its people. But you are going to know.
