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

Those of you who turned back on the day the two armies met, Satan caused them to stumble due to some of their deeds. But God has forgiven them. God is Forgiving and Forbearing.
