Al-A'raf - 7:105

حَقِيقٌ عَلَى أَن لاَّ أَقُولَ عَلَى اللّهِ إِلاَّ الْحَقَّ قَدْ جِئْتُكُم بِبَيِّنَةٍ مِّن رَّبِّكُمْ فَأَرْسِلْ مَعِيَ بَنِي إِسْرَائِيلَ
[7:105]
(I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel
One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me."
Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me.
