The hadiths state Imam Mahdi (a) is son of Hassan Al-Askari (a) in twelver sources. The Bahai faith most recent Prophet didn't dismiss these hadiths as fabricated, but said, he is a spiritual son of Hassan Al-Askari (a), even though Hassan Al-Askari (a) didn't have children aside from Imam Mahdi (a).
I am going to argue the hadiths give context to the meaning son. Believers per hadiths are born out of Imams and it can be argued they are spiritually their sons and Imams their fathers. These hadiths have a context, and the hadiths of Twelve Imams (a) naming them son after son also have a context. For example, there is a hadith of Mohammad (s) and Ali (a) being the parents of this nation.
Also from another perspective only the Imams (a) can be true sons of Mohammad (s) as many hadiths show this as well as confirmed by the concept of chosen family in the Quran. So it depends on the context, what is being said.
To mix the metaphor context with the literal context is being unfair to speech.
I will start from Misbahal Shariah:
My argument here is the context of lineage is literal. Before that Imams (a) were stated to be lights that glorified God 14 000 years before he created anything else. Salman was wondering because Imams (a) are light, is it good enough to just recognize them as lights or perhaps, that they will be born in the future, but their names and lineage doesn't need to be known now by believers. The Rasool (s) says no you have to know their names and lineage.
I will share more hadiths.

I will start from Misbahal Shariah:
"O Messenger of Allah, is there belief without knowing their names and lineage?"
"No, Salman."
"Messenger of Allah, where will I find them?"
"You already know al-Husayn; then there will be the master of the worshippers, 'Ali ibn Husayn (Zayn al-'Abidin); then his son Muhammad ibn 'Ali, the piercer of the knowledge of the early and the later prophets and messengers (al-Baqir); then Ja'far ibn Muhammad, the truthful tongue of Allah (al-Sadiq); then Musa ibn Ja'far, the one who kept his rage silent through patience in Allah (al-Kadhim); then 'Ali ibn Musa, pleased with the secret of Allah (al-Rida '); then Muhammad ibn 'Ali, the chosen one from the creatures of Allah (al-Mukatar); then 'Ali ibn Muhammad, the guide to Allah (al-Hadi); then al-Hasan, son of 'Ali, the silent, trustworthy guardian over the secret of Allah (al-'Askari); then mim ha' mim dal (Muhammad), called Ibn al-Hasan, the announcer who establishes the right of Allah."
