وقال رجل مؤمن من آل فرعون يكتم إيمانه أتقتلون رجلا أن يقول (40:28) بالانجليزي

(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."
