وَأَمَّا الْغُلَامُ فَكَانَ أَبَوَاهُ مُؤْمِنَيْنِ فَخَشِينَا أَن يُرْهِقَهُمَا طُغْيَانًا وَكُفْرًا
[18:80]
And as for the boy, his parents were believers and we feared lest he should make disobedience and ingratitude to come upon them:
"As for the youth, his parents were people of Faith, and we feared that he would grieve them by obstinate rebellion and ingratitude (to Allah and man).
And as for the lad, his parents were believers and we feared lest he should oppress them by rebellion and disbelief.
