Surat Ghāfir - سورة غافر

وَقَالَ رَجُلٌ مُّؤْمِنٌ مِّنْ آلِ فِرْعَوْنَ يَكْتُمُ إِيمَانَهُ أَتَقْتُلُونَ رَجُلًا أَن يَقُولَ رَبِّيَ اللَّهُ وَقَدْ جَاءَكُم بِالْبَيِّنَاتِ مِن رَّبِّكُمْ ۖ وَإِن يَكُ كَاذِبًا فَعَلَيْهِ كَذِبُهُ ۖ وَإِن يَكُ صَادِقًا يُصِبْكُم بَعْضُ الَّذِي يَعِدُكُمْ ۖ إِنَّ اللَّهَ لَا يَهْدِي مَنْ هُوَ مُسْرِفٌ كَذَّابٌ

: 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!
