When the Prophet ﷺ congratulated a man on his marriage, he said: May Allah bless for you, and may He bless on you, and combine both of you in good (works).  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا رَفَّأَ الإِنْسَانَ إِذَا تَزَوَّجَ قَالَ بَارَكَ اللَّهُ لَكَ وَبَارَكَ عَلَيْكَ وَجَمَعَ بَيْنَكُمَا فِي خَيْرٍ
