إِنَّ الَّذينَ تَوَلَّوا مِنكُم يَومَ التَقَى الجَمعانِ إِنَّمَا استَزَلَّهُمُ الشَّيطانُ بِبَعضِ ما كَسَبوا ۖ وَلَقَد عَفَا اللَّهُ عَنهُم ۗ إِنَّ اللَّهَ غَفورٌ حَليمٌ

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.
