Why were the Hadith recorded more than a century after Prophet Muhammadโs (PBUH) death? They had no internet, they had no books and they could not read or write.
Most of the people at this time were unlettered. They had memories so powerful that they knew their own lineage from 7 generations back!
We canโt do this nowadays. Watch this to understand why it took so long to record the hadith.
