Ghafir 40:28

Waqala rajulun mu/minun min alifirAAawna yaktumu eemanahu ataqtuloona rajulan an yaqoolarabbiyya Allahu waqad jaakum bilbayyinatimin rabbikum wa-in yaku kathiban faAAalayhi kathibuhuwa-in yaku sadiqan yusibkum baAAdu allatheeyaAAidukum inna Allaha la yahdee man huwa musrifunkaththab

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.

And said a believing man from the House of Pharaoh who had kept his faith secret, “Would you kill a man because he says - ‘Allah is my Lord’ - while he has come to you with clear signs from your Lord? If he is a liar, his lie will fall back on himself, and if he is truthful, some of that (punishment) of which he warns you will afflict you. Indeed, Allah does not give guidance to anyone who is transgressor, a liar.
