Al-Anfal - 8:48

وَإِذْ زَيَّنَ لَهُمُ الشَّيْطَانُ أَعْمَالَهُمْ وَقَالَ لاَ غَالِبَ لَكُمُ الْيَوْمَ مِنَ النَّاسِ وَإِنِّي جَارٌ لَّكُمْ فَلَمَّا تَرَاءتِ الْفِئَتَانِ نَكَصَ عَلَى عَقِبَيْهِ وَقَالَ إِنِّي بَرِيءٌ مِّنكُمْ إِنِّي أَرَى مَا لاَ تَرَوْنَ إِنِّيَ أَخَافُ اللّهَ وَاللّهُ شَدِيدُ الْعِقَابِ
[8:48]
And when the Shaitan made their works fair seeming to them, and said: No one can overcome you this day, and surely I am your protector: but when the two parties came in sight of each other he turned upon his heels, and said: Surely I am clear of you, surely I see what you do not see, surely I fear Allah; and Allah is severe in requiting (evil).
Remember Satan made their (sinful) acts seem alluring to them, and said: "No one among men can overcome you this day, while I am near to you": But when the two forces came in sight of each other, he turned on his heels, and said: "Lo! I am clear of you; lo! I see what ye see not; Lo! I fear Allah: for Allah is strict in punishment."
And when Satan made their deeds seem fair to them and said: No-one of mankind can conquer you this day, for I am your protector. But when the armies came in sight of one another, he took flight, saying: Lo! I am guiltless of you. Lo! I see that which ye see not. Lo! I fear Allah. And Allah is severe in punishment.
