Trace back sources for knowledge authentically

This hadith is about the chain of narrators who narrated a certain hadith. It is important to note that when it comes to Islamic teachings, it is essential to know the source and authenticity of any information being shared or discussed. The chain of narrators helps us trace back the origin and source of any particular hadiths or teachings so that we can be sure that they are authentic and reliable sources for our knowledge. In this case, Qutaiba b. Sa'id and Zubair b. Harb were two people who reported this particular hadith on the authority of Jarir who was reporting on behalf of A'mash with a same chain of narrators as mentioned above in order to ensure its authenticity before sharing it with others for further discussion or learning purposes.
