ﺗﻬنئة المولود له وجوابه
بَارَكَ اللَّهُ لَكَ فِي الْمَوْهُوبِ لَكَ، وَشَكَرْتَ الْوَاهِبَ، وَبَلَغَ أَشُدَّهُ، وَرُزِقْتَ بِرَّهُ. وَيَرُدُّ عَلَيْهِ الْمُهَــــــنَّأُ فَيَقُولُ: بَارَكَ اللَّهُ لَكَ وَبَارَكَ عَلَيْكَ، وَجَزَاكَ اللَّهُ خَيْراً، وَرَزَقَكَ اللَّهُ مِثْلَهُ، وَأَجْزَلَ ثَوَابَكَ.
May Allah bless you in what He has given you, may you thank the Giver, may the child reach maturity and may you be granted its kindness. The one who is congratulated replies: May Allah bless you and shower His blessings upon you, may Allah reward you with good, grant you the like and multiply your reward.
