Qur'an 28:13 Al-Qasas

فَرَدَدْنَٰهُ إِلَىٰٓ أُمِّهِۦ كَىْ تَقَرَّ عَيْنُهَا وَلَا تَحْزَنَ وَلِتَعْلَمَ أَنَّ وَعْدَ ٱللَّهِ حَقٌّۭ وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ

So We restored him to his mother that she might be content and not grieve and that she would know that the promise of Allah is true. But most of the people do not know.
