Allah said:

ثُمَّ بَعَثْنَا

(Then after them We sent ) meaning ofter these Messengers,

مُّوسَى وَهَـرُونَ إِلَى فِرْعَوْنَ وَمَلَئِهِ

فَلَمَّا جَآءَهُمُ الْحَقُّ مِنْ عِندِنَا قَالُواْ إِنَّ هَـذَا لَسِحْرٌ مُّبِينٌ

(So, when came to them the truth from us, they said: "This is indeed clear magic.") They were as if they gave an oath that what they had said was the truth. But they knew that what they were saying was a mere lie. As Allah said:

وَجَحَدُواْ بِهَا وَاسْتَيْقَنَتْهَآ أَنفُسُهُمْ ظُلْماً وَعُلُوّاً

(And they belied them wrongfully and arrogantly, though they themselves were convinced thereof. )(27:14) Musa criticized them saying:

أَتقُولُونَ لِلْحَقِّ لَمَّا جَآءَكُمْ أَسِحْرٌ هَـذَا وَلاَ يُفْلِحُ السَّـحِرُونَقَالُواْ أَجِئْتَنَا لِتَلْفِتَنَا

("Say you (this) about the truth when it has come to you Is this magic But the magicians will never be successful." They said: "Have you come to us to turn us away...)

عَمَّا وَجَدْنَا عَلَيْهِ ءابَاءَنَا

وَتَكُونَ لَكُمَا
