﴿ وَأَمَّا ٱلْغُلَٰمُ فَكَانَ أَبَوَاهُ مُؤْمِنَيْنِ فَخَشِينَآ أَن يُرْهِقَهُمَا طُغْيَٰنًۭا وَكُفْرًۭا ﴾

“"And as for that young man, his parents were [true] believers - whereas we had every reason to fear that he would bring bitter grief upon them by [his] overweening wickedness and denial of all truth:”

And as for the boy, his parents, who were the spirit and physical nature, were believers, affirmers of the Oneness by virtue of their yielding as they wayfare in obedience of God, submit to God's command and comply with what God desires from them; and We feared lest he should overwhelm them, totally cover them, with insolence, towards them by manifesting himself in his I-ness at the presential vision of the spirit, and ingratitude, towards the grace of having them by his disobedience and evil action; or with ingratitude for the veil so that he ends up spoiling for them their affair and their religion and invalidating [for them] their servanthood of God.
