Surah Al-Kahf, ayah 80

وَأَمَّا ٱلۡغُلَٰمُ فَكَانَ أَبَوَاهُ مُؤۡمِنَيۡنِ فَخَشِينَآ أَن يُرۡهِقَهُمَا طُغۡيَٰنٗا وَكُفۡرٗا ٨٠

Wa ammal-ghulāmu fakāna abawāhu mu'minayni fakhashīnā an yurhiqahumā tughyānan wakufrā

And as for the boy, his parents were believers, and we feared that he would overburden them by transgression and disbelief.
