Aqeel bin Abu Talib married a woman from Bani Jusham, and people said to him, "May you have harmony and many sons."He replied, "Say instead what the Messenger of Allah ﷺ said, 'May Allah bless you and bestow His blessings upon you.'"
تزوج عقيل بن أبي طالب امرأة من بني جشم، فقيل له: بالرفاء والبنين. قال: قولوا كما قال رسول الله ﷺ: بارك الله فيكم، وبارك لكم.
It was narrated by Nasai (3371), and this is his wording, Ibn Majah (1906), Ahmad (1739), Bayhaqi (7/148), and Darimi (2119), all of them through various routes from Hasan, who said what has been mentioned. Bayhaqi's wording is, "Aqeel bin Abu Talib came to Basra." Hasan lived to witness roughly forty years of Aqeel's life, so it is not unlikely that Aqeel's coming to Basra occurred during that period. His being a mudallis does not cause a problem here, because he is narrating a story that took place in his own time.The hadith has another route, which is what Imam Ahmad narrated (1738), from Hakam bin Nafi, who said, Ismail bin Ayyash narrated to us, from Salim bin Abdullah, from Abdullah bin Muhammad bin Aqeel, who said, Aqeel bin Abu Talib got married and came out to us, so we said, "May it bring you comfort and sons." He said, "No, do not say that, for the Prophet ﷺ forbade us from saying it and said, 'Say instead, may Allah bless you, and may Allah bless her.'"What Ismail bin Ayyash narrates from the people of Hijaz is not sahih, and this narration is one of those cases. However, it is not necessarily the case that he erred in it, since it is corroborated by another narration. It also contains Abdullah bin Muhammad bin Aqeel, who did not live to meet his grandfather Aqeel, since he died in the year 142 AH, while Aqeel died in 60 AH. Still, this is a hadith belonging to the household, which suggests he heard it from members of his own family. The two routes strengthen one another. The hadith also has other routes.
