Quran 43:49 — Ornaments (Al-Zukhruf)

وَقالوا يٰأَيُّهَ السّاحِرُ ادعُ لَنا رَبَّكَ بِما عَهِدَ عِندَكَ إِنَّنا لَمُهتَدونَ

They said, "O you magician, implore your Lord on our behalf, since you have an agreement with Him (to relieve this plague);we will then be guided."

[43:48] Every sign we showed them was bigger than the one before it. We afflicted them with the plagues, perhaps they repent.

[43:50] But as soon as we relieved their affliction, they reverted.
