Surah Ghafir, verse 28

وَقَالَ رَجُلٌ مُّؤْمِنٌ مِّنْ ءَالِ فِرْعَوْنَ يَكْتُمُ إِيمَـٰنَهُۥٓ أَتَقْتُلُونَ رَجُلًا أَن يَقُولَ رَبِّىَ ٱللَّهُ وَقَدْ جَآءَكُم بِٱلْبَيِّنَـٰتِ مِن رَّبِّكُمْ ۖ وَإِن يَكُ كَـٰذِبًا فَعَلَيْهِ كَذِبُهُۥ ۖ وَإِن يَكُ صَادِقًا يُصِبْكُم بَعْضُ ٱلَّذِى يَعِدُكُمْ ۖ إِنَّ ٱللَّهَ لَا يَهْدِى مَنْ هُوَ مُسْرِفٌ كَذَّابٌ ﴿٢٨﴾

40:28 A believing man from the house of Pharaoh, who was concealing his faith, said, “Would you kill a man simply because he says: ‘My Lord is Allah,’ even though he has come to you with clear proofs from your Lord? If he is a liar, he will suffer the consequences of his lie, but if he is truthful, some of what he is threatening you with will befall you. Surely Allah does not guide anyone who is a transgressor and an utter liar
