And a believing man from the family of Pharaoh who concealed his (40:28)

Almuntakhab Fi Tafsir Alquran Alkarim

And there said a man of pharaonic parents, whose heart had been impressed with the image of religious and spiritual virtues but had hidden his faith: Will you slay a man just because he says The One object of supreme adoration and the end and the purpose for which I am destined is Allah, my Creator. And he has already bought you clear evidence demonstrating Allahs Omnipotence and Authority and brings you to your senses! And if he happens to be lying and conveying a false impression he will only much hurt himself and his interest and the fault will be at his own door But if what he says is in conformity with truth and in agreement with reality then you shall be wed to some of the calamities he has promised you anal you will have brought suffering upon yourselves. Allah certainly does not guide to His path of righteousness any one who goes beyond just and prescribed limits and lies in his teeth

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(40:28) Then a man endowed with faith, from Pharaoh's folk, who had kept his faith hidden, said: 'Do you kill a person simply because he says: 'My Lord is Allah' even though he brought to you clear Signs from your Lord? *45 If he is a liar, his lying will recoil upon him; *46 but if he is truthful, you will be smitten with some of the awesome consequences of which he warns you. Allah does not guide to the Right Way any who exceeds the limits and is an utter liar. *47

*45) That is, "He has shown such manifest Signs to you as have made it absolutely clear that he is a Messenger sent by your Lord." The Believer, from among the people of Pharaoh, was obviously referring to the Signs the details of which have already been given in AI-A'raf: 107-117,130-133; Bani Isra'il: 101-102; Ta Ha: 56-73; Ash-Shu'ara': 30-51; An-Naml :10-13).
*46) That is, "If in spite of such manifest Signs as he has shown you, you regard him as a liar, you should leave him alone, for the alternative probability, and a very strong probability too, is that he is truthful, and therefore you may involve yourselves in God's torment by laying your hands on him. Therefore, even if you think that he is a liar, you should leave him to himself. For if he is lying, in the name of Allah, Allah Himself will take him to task." Similar words had the Prophet Moses himself said to Pharaoh before this: "If you do not believe in me, do not harm me." (Ad-Dukhan: 21)
Here one should keep in mind that the Believer of the people of Pharaoh had not openly disclosed in the beginning that he had affirmed faith in the Prophet Moses, but he spoke as if he also belonged to Pharaoh's side, and was only wishing his people well. But when Pharaoh and his courtiers did not seem to see reason and continued to behave stubbornly, he at last disclosed the secret of his faith, as becomes obvious from his speech in vv. 38-44.
*47) This sentence can have two meanings and probably the Believer had intentionally employed it, because he did not yet want to express his belief openly. Its one meaning is: "One and the same person cannot combine righteousness and lying and falsehood. You can clearly see that Moses is a man of very sublime and pure character. Therefore, how can you believe that, on the one hand, he should be such a liar as to lay a baseless claim to prophethood in the name of Allah, and on the other, Allah should bless him with such high morals?" The other meaning is: "If you arc bent upon taking the life of Moses (peace be upon him) by transgressing alI limits and will execute your evil designs by bringing false accusations against him, you should remember that Allah will never show you the way to success."

اس موقع پر آل فرعون میں سے ایک مومن شخص، جو اپنا ایمان چھپائے ہوئے تھا، بول اٹھا: "کیا تم ایک شخص کو صرف اِس بنا پر قتل کر دو گے کہ وہ کہتا ہے میرا رب اللہ ہے؟ حالانکہ وہ تمہارے رب کی طرف سے تمہارے پاس بینات لے آیا اگر وہ جھوٹا ہے تو اس کا جھوٹ خود اسی پر پلٹ پڑے گا لیکن اگر وہ سچا ہے تو جن ہولناک نتائج کا وہ تم کو خوف دلاتا ہے ان میں سے کچھ تو تم پر ضرور ہی آ جائیں گے اللہ کسی شخص کو ہدایت نہیں دیتا جو حد سے گزر جانے والا اور کذاب ہو
