ALI 'IMRAN — Ayat 155

إِنَّ الَّذِينَ تَوَلَّوْاْ مِنكُمْ يَوْمَ الْتَقَى الْجَمْعَانِ إِنَّمَا اسْتَزَلَّهُمُ الشَّيْطَانُ بِبَعْضِ مَا كَسَبُواْ وَلَقَدْ عَفَا اللّهُ عَنْهُمْ إِنَّ اللّهَ غَفُورٌ حَلِيمٌ

Indeed, those of you who turned back on the day the two armies met, it was Satan who caused them to slip because of some [blame] they had earned. But Allah has already forgiven them. Indeed, Allah is Forgiving and Forbearing.
