Abu Huraira reported the same hadith which is transmitted to us by another chain of transmitters, e. g. Muhammad b. al-Muthanna, Ishaq b. Yusuf Azraq, Ibn 'Aun, etc.
The transmission of knowledge has been an integral part in Islamic tradition since its inception as it allows for the preservation and spread of teachings throughout generations without any distortion or alteration in meaning or context. By passing on these teachings we are able to ensure that our culture remains intact even after centuries have passed by allowing future generations to benefit from them just like we do today.
