Qur'an 8:48

وَإِذْ زَيَّنَ لَهُمُ ٱلشَّيْطَـٰنُ أَعْمَـٰلَهُمْ وَقَالَ لَا غَالِبَ لَكُمُ ٱلْيَوْمَ مِنَ ٱلنَّاسِ وَإِنِّى جَارٌ لَّكُمْ ۖ فَلَمَّا تَرَآءَتِ ٱلْفِئَتَانِ نَكَصَ عَلَىٰ عَقِبَيْهِ وَقَالَ إِنِّى بَرِىٓءٌ مِّنكُمْ إِنِّىٓ أَرَىٰ مَا لَا تَرَوْنَ إِنِّىٓ أَخَافُ ٱللَّهَ ۚ وَٱللَّهُ شَدِيدُ ٱلْعِقَابِ

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.
