Hadeeth of 'Aqeel bin Abi Talib
From Musnad Ahmad
It was narrated that ‘Abdullah bin Muhammad bin "Aqeel said:
’Aqeel bin Abi Talib got married. He came out to us and we said: May you live in harmony and be given sons. He said: Stop; do not say that, because the Prophet (ﷺ) told us not to say that, and he said: "Say: May Allah bless you and bless her for you.”

It was narrated from alHasan that
"Aqeel bin Abi Talib (رضي الله عنه) married a woman from Banu Jusham. The people entered upon him and said: May you live in harmony and be given sons. He said: Do not say that. They said: What should we say, O Abu Yazeed? He said: Say: May Allah bless you and send blessings upon you. This is what we were instructed to say.
