Nowadays a lot of people quote/post things and then attribute it to the Prophet صلى الله عليه وسلم. They do not verify its authenticity nor do they quote the references. Moreover, they do not even mention the name of the companion who narrated that Hadeeth. Before quoting any Hadeeth, its authenticity should be verified, because people in the past have concocted/fabricated many narrations of their own and then attributed it to Prophet صلى الله عليه وسلم for various reasons. The following Ahadeeth convey to us the gravity of the sin for quoting a Hadeeth before verifying its authenticity.
