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

“And thus We restored him to his mother, so that her eye might he gladdened, and that she might grieve no longer, and that she might know that God’s promise always comes true - even though most of them know it not!”

وَأَوْحَيْنَا إِلَىٰ أُمِّ مُوسَىٰ (28:7) The word Wahy (inspiration) is used here in its literal meaning. It does not mean the Wahy that is peculiar to prophets. This point has already been explained under Surah Taha.
