Surah Ghafir
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
Wa qāla rajulum mu'min(um), min āli fir‘auna yaktumu īmānahū ataqtulūna rajulan ay yaqūla rabbiyallāhu wa qad jā'akum bil-bayyināti mir rabbikum, wa iy yaku kāżiban fa ‘alaihi każibuh(ū), wa iy yaku ṣādiqay yuṣibkum ba‘ḍul-lażī ya‘idukum, innallāha lā yahdī man huwa musrifun każżāb(un).
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 Allah' 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, Allah does not guide one who is a transgressor and a liar.
