Sunan an-Nasai
حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ، وَمُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالاَ حَدَّثَنَا خَالِدٌ، عَنْ أَشْعَثَ، عَنِ الْحَسَنِ، قَالَ تَزَوَّجَ عَقِيلُ بْنُ أَبِي طَالِبٍ امْرَأَةً مِنْ بَنِي جُشَمٍ فَقِيلَ لَهُ بِالرِّفَاءِ وَالْبَنِينِ . قَالَ قُولُوا كَمَا قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " بَارَكَ اللَّهُ فِيكُمْ وَبَارَكَ لَكُمْ " .
It was narrated that Al-Hasan said: "Aqil bin Abi Talib married a woman from Banu Jusham, and it was said to him: 'May you live in harmony and have many sons.' He said: 'Say what the Messenger of Allah said: Barak Allahu fikum, wa baraka lakum. (May Allah bless you and bestow blessings upon you.)'"
