Ali 'Imran 3:154 ثم انزل عليكم من بعد الغم امنة نعاسا يغشى طايفة منكم وطايفة قد اهمتهم انفسهم يظنون بالله غير الحق ظن الجاهلية يقولون هل لنا من الامر من شيء قل ان الامر كله لله يخفون في انفسهم ما لا يبدون لك يقولون لو كان لنا من الامر شيء ما قتلنا هاهنا قل لو كنتم في بيوتكم لبرز الذين كتب عليهم القتل الى مضاجعهم وليبتلي الله ما في صدوركم وليمحص ما في قلوبكم والله عليم بذات الصدور ١٥٤

After (the excitement) of the distress, He sent down calm on a band of you overcome with slumber, while another band was stirred to anxiety by their own feelings, Moved by wrong suspicions of Allah-suspicions due to ignorance. They said: "What affair is this of ours?" Say thou: "Indeed, this affair is wholly Allah's." They hide in their minds what they dare not reveal to thee. They say (to themselves): "If we had had anything to do with this affair, We should not have been in the slaughter here." Say: "Even if you had remained in your homes, those for whom death was decreed would certainly have gone forth to the place of their death"; but (all this was) that Allah might test what is in your breasts and purge what is in your hearts. For Allah knoweth well the secrets of your hearts.
