فَرَدَدۡنَٰهُ إِلَىٰٓ أُمِّهِۦ كَيۡ تَقَرَّ عَيۡنُهَا وَلَا تَحۡزَنَ وَلِتَعۡلَمَ أَنَّ وَعۡدَ ٱللَّهِ حَقّٞ وَلَٰكِنَّ أَكۡثَرَهُمۡ لَا يَعۡلَمُونَ ١٣
Faradadnāhu ilā ummihī kay taqarra ʿaynuhā wa lā taḥzana walitaʿlama anna waʿdallāhi ḥaqquw wa lākinna aktharahum lā yaʿlamūn.
So We restored him to his mother that she might be content and not grieve and that she would know that the promise of Allāh is true. But most of them [i.e., the people] do not know.
