First I have heard of it.
Regarding the authors of the hadeeth: are there certain authors that you outright know as false? If so, are you willing to name them?
basically the main collections of hadith
for example Saheeh bukhari...contain hadiths within them coming from many different sources (ie the chain of transmission being different for most hadiths)
some contradict others
so somewhere down the line the chain of transmission is broken...ie like chinese whispers.
Imam Bukhari judged the validity of the source based on his own criteria..yet when there were contradictions, he was just being fair in presenting all of them.
so we have to make a calculated decision in deciding which story is correct
for example there are the hadiths which claim aisha's age was '9' at the age of consumation in Sahih bukhari which you know about.
however a clever person thinks outside the box and can understand a few things
1) aisha was accused of being an adulteress, by the shia camp who were pro-Ali/Fatimah and anti-Abu Bakr/Aisha
2) These specific hadith MAY have been politically influenced to contrast the shia claim, by presenting aisha as a 'pure' child virgin.
3) here is another hadith in the same book Sahih bukhari)
same "narrator" ie Aisha
but the chain of transmission is going to b
(3) Narrated 'Aisha: (the wife of the Prophet) I had seen my parents following Islam since I attained the age of puberty. Not a day passed but the Prophet visited us, both in the mornings and evenings. My father Abii Bakr thought of building a mosque in the courtyard of his house and he did so. He used to pray and recite the Qur'an in it. The pagan women and their children used to stand by him and look at him with surprise. Abu Bakr was a Softhearted person and could not help weeping while reciting the Quran. The chiefs of the Quraish pagans became afraid of that (i.e. that their children and women might be affected by the recitation of Quran)." (Book #8, Hadith #465)
Aisha was the daughter of Abu Bakr who was the 3rd convert to islam when the Prophet SAW was 40 years old.
Here, "Aisha" is saying she had already attained the age of puberty when her parents accepted islam.
so if she married the Prophet SAW 13 years later, it would put her in her 20s.
4) if hadith contradict the Quran, we are meant to reject them.
The Quran doesn't allow us to marry children
Prove orphans till they reach the marriageable age; then, if ye find them of sound judgment, deliver over unto them their fortune; and devour it not by squandering and in haste lest they should grow up Whoso (of the guardians) is rich, let him abstain generously (from taking of the property of orphans); and whoso is poor let him take thereof in reason (for his guardianship). And when ye deliver up their fortune unto orphans, have (the transaction) witnessed in their presence. Allah sufficeth as a ReckonerQuran 4:6
The hadith are collections of narrations attributes to a primary source, but they are stories that were memorised/passed on so over time you have a chain of transmission
so a hadith scholar would have to analyse the entire chain ie each individual and their backstory to know how trustworthy the source was
there are question marks hanging over the narrations that present aisha's age as 9 at the time her marraige was consumated.
This is something i guess you'd have to be willing to read up on in depth if you were yourself, interested.
You cannot just write off an entire collection (ie Saheeh Bukhari)...even if you considered some hadith to be false within it, you still have to accept them as a real source of information that once existed and was written down.
