What is the origin of the hadith, "The hadith that was compiled and preserved," narrated from Khalid ibn al-Walid, may Allah be pleased with him, in which it is stated: "O Messenger of Allah, I came to ask you about what will suffice me in this world and the Hereafter. So the Messenger of Allah, peace and blessings be upon him, said: 'Ask whatever you wish.' He said: 'I want to be the most knowledgeable of people.' So the Messenger of Allah, peace and blessings be upon him, said: 'Fear Allah, and you will be the most knowledgeable of people'"? And what is the ruling on disseminating hadiths without verifying their authenticity?

The aforementioned Hadith is not found in the well-known books of Sunnah. It was found in the book Kanz al-Ummal without attribution or chain of narration (isnad), and its context indicates that it is a fabricated Hadith attributed to the Prophet, peace and blessings be upon him. Therefore, one must be cautious about believing in it or propagating it. It is incumbent upon a Muslim not to spread any Hadith until its authenticity is verified, otherwise, they would fall under the warning of the Prophet, peace and blessings be upon him, against lying about him: "Indeed, lying about me is not like lying about anyone else. Whoever intentionally lies about me, let him take his seat in the Hellfire."
