self-delusion and false hope

يُنَادُونَهُمْ أَلَمْ نَكُن مَّعَكُمْ ۖ قَالُوا۟ بَلَىٰ وَلَـٰكِنَّكُمْ فَتَنتُمْ أَنفُسَكُمْ وَتَرَبَّصْتُمْ وَٱرْتَبْتُمْ وَغَرَّتْكُمُ ٱلْأَمَانِىُّ حَتَّىٰ جَآءَ أَمْرُ ٱللَّهِ وَغَرَّكُم بِٱللَّهِ ٱلْغَرُورُ

They [i.e., the hypocrites] will call to them [i.e., the believers], "Were we not with you?" They will say, "Yes, but you afflicted yourselves and awaited [misfortune for us] and doubted, and wishful thinking deluded you until there came the command of Allāh. And the Deceiver [i.e., Satan] deceived you concerning Allāh.
