Offering congratulations on the occasion of marriage Sunan Ibn Majah 1906

Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا أَشْعَثُ، عَنِ الْحَسَنِ، عَنْ عَقِيلِ بْنِ أَبِي طَالِبٍ، أَنَّهُ تَزَوَّجَ امْرَأَةً مِنْ بَنِي جُشَمٍ فَقَالُوا بِالرِّفَاءِ وَالْبَنِينَ فَقَالَ لاَ تَقُولُوا هَكَذَا وَلَكِنْ قُولُوا كَمَا قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ اللَّهُمَّ بَارِكْ لَهُمْ وَبَارِكْ عَلَيْهِمْ ‏"
Translation
It was narrated from `Aqil bin Abu Talib

that he married a woman from Banu Jusham, and they said: “May you live in harmony and have many sons.” He said: “Do not say that, rather say what the Messenger of Allah said: 'Allahumma barik lahum wa barik `alaihim (O Allah, bless them and bestow blessings upon them).' ”
