Quran 28:13 Al-Qasas, ayah 13 of 88

فَرَدَدْنَـٰهُ إِلَىٰٓ أُمِّهِۦ كَىْ تَقَرَّ عَيْنُهَا وَلَا تَحْزَنَ وَلِتَعْلَمَ أَنَّ وَعْدَ ٱللَّهِ حَقٌّ وَلَـٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ ۝١٣

28:13 So We restored him to his mother that she might be comforted and not grieve, and that she might know that the promise of Allah is true. But most of them know not.
