Surah Az-Zukhruf — Ayah 49 (43:49)
وَقَالُواْ يَٰٓأَيُّهَ ٱلسَّاحِرُ ٱدۡعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَ إِنَّنَا لَمُهۡتَدُونَ ٤٩
English translation (Saheeh International)
And they said [to Moses], "O magician, invoke for us your Lord by what He has promised you. Indeed, we will be guided."
Brief commentary
So when some of the punishment came upon them, they said to Moses (peace be upon him), “O sorcerer! Pray to your Lord for us asking Him to remove this punishment just as He said He would if we believed. If it is removed from us, we will be guided to the truth.”
