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.)'"
