Ghafir 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

waqāla rajulun mu'minun min āli fir'ʿawna yaktumu īmānahu ataqtulūna rajulan an yaqūla rabbiya l-lahu waqad jāakum bil-bayināti min rabbikum wa-in yaku kādhiban faʿalayhi kadhibuhu wa-in yaku ṣādiqan yuṣib'kum baʿḍu alladhī yaʿidukum inna l-laha lā yahdī man huwa mus'rifun kadhābun

And a believing man from the family of Pharaoh who concealed his faith said, "Do you kill a man [merely] because he says, 'My Lord is Allāh' while he has brought you clear proofs from your Lord? And if he should be lying, then upon him is [the consequence of] his lie; but if he should be truthful, there will strike you some of what he promises you. Indeed, Allāh does not guide one who is a transgressor and a liar.
