Warning against lying about the Prophet (peace and blessings be upon him), with mention of some hadiths indicating this.

The Shaykh : And we see, with great regret, that most of today's Islamic preachers do not pay any attention whatsoever to these two sciences. Rather, they are content merely to transmit whatever they wish to cite from the hadith from any book that falls into their hands, without distinguishing or verifying what they have transmitted. This is a neglect of the care for the hadith of the Prophet (peace and blessings be upon him) in the first place, and then it is a lack of response from these Muslims to the hadiths of the Messenger (peace and blessings be upon him) that warn the Muslim not to narrate a hadith from him before verifying its authenticity. All of you know the saying of the Messenger (peace and blessings be upon him): . This is known to everyone. However, there is a hadith containing a severe reminder for these people who are lax in transmitting hadiths without verifying their authenticity or weakness. It is his saying (peace and blessings be upon him): , . If the authors and writers of the present era were to adhere to this hadith, many of them would not be able to roam freely in much of their writing, because the burden of these writings is nothing but weak hadiths that have no chains of narration, no strength, and no control.
And there is another hadith in which he (peace and blessings be upon him) says: . The first hadith is: . People might say: We do not intentionally lie about the Messenger of Allah (peace and blessings be upon him). But the Prophet (peace and blessings be upon him), in this last hadith, which is his saying: . This last hadith warns the Muslim not to narrate a hadith whose authenticity he does not know, which is suspected to be fabricated. If he narrates it and it is indeed so, and he did not verify it before narrating it, then he is one of the two liars. The first liar is the one who fabricated it, and the other liar is the one who promoted it and spread it among the people. If there were nothing in this chapter but this hadith, the awareness of Muslims today would be the awareness of the scholars of knowledge; they would not narrate a hadith unless they had verified its authenticity.
So, if the cure for the condition of Muslims today is returning to the religion, and this religion is the religion that was revealed to the heart of Muhammad (peace and blessings be upon him) before what entered into it, especially these weak and fabricated hadiths, then it was necessary, indeed a fundamental matter that is indispensable and without which all matters... today for the renewal of Islamic life, except by following this path that leads Muslims to knowing the religion that was in the time of the Prophet (peace and blessings be upon him). This is one thing.
