بَارَكَ اللَّهُ لَكَ فِي الْمَوْهُوبِ لَكَ، وَشَكَرْتَ الْوَاهِبَ، وَبَلَغَ أَشُدَّهُ، وَرُزِقْتَ بِرَّهُ
Baarakallaahu laka fil-mawhoobi laka, wa shakartal-waahiba, wa balagha ‘ashuddahu, wa ruziqta birrahu.
May Allah bless you with His gift to you, and may you (the new parent) give thanks, may the child reach the maturity of years, and may you be granted its righteousness.
