Prophetic courage and conviction

قَالَ رَبُّكُمْ وَرَبُّ ءَابَآئِكُمُ ٱلْأَوَّلِينَ

[Moses] said, "Your Lord and the Lord of your first forefathers."

فَإِنَّهُمْ عَدُوٌّ لِّىٓ إِلَّا رَبَّ ٱلْعَـٰلَمِينَ

Indeed, they are enemies to me, except the Lord of the worlds,

وَلَقَدْ أَرْسَلْنَا مُوسَىٰ بِـَٔايَـٰتِنَآ إِلَىٰ فِرْعَوْنَ وَمَلَإِي۟هِۦ فَقَالَ إِنِّى رَسُولُ رَبِّ ٱلْعَـٰلَمِينَ

And certainly did We send Moses with Our signs to Pharaoh and his establishment, and he said, "Indeed, I am the messenger of the Lord of the worlds."
