And a believing man of Fir'aun's (Pharaoh) family, who hid his faith said: "Would you kill a man because he says: My Lord is Allah, and he has come to you with clear signs (proofs) from your Lord? And if he is a liar, upon him will be (the sin of) his lie; but if he is telling the truth, then some of that (calamity) wherewith he threatens you will befall on you." Verily, Allah guides not one who is a Musrif (a polytheist, or a murderer who shed blood without a right, or those who commit great sins, oppressor, transgressor), a liar!
