Why isn't the story of the Dajjal mentioned in the Muwatta despite its fame among the people of Medina, and does this indicate its weakness?

Belief in the emergence of the Antichrist (Al-Masih Ad-Dajjal) at the End of Times is a tenet of Ahlus-Sunnah (definition) wal-Jama'ah (the People of the Sunnah and the Community), and authentic hadiths regarding it have reached the level of continuous transmission (Tawatur). As for the claim that Imam Malik's failure to mention the story of the Dajjal in "Al-Muwatta'" is evidence of its weakness, this is incorrect; Imam Malik actually narrated four hadiths about the Dajjal in his Muwatta'. If the hadith (definition) of "Al-Jassasah" is what is meant, then it is authentic and was transmitted by Imam Muslim. Imam Malik's not including it in "Al-Muwatta'" does not undermine its authenticity, as Malik did not encompass all authentic hadiths in his Muwatta', which was predominantly characterized by its jurisprudential nature. Moreover, this hadith was narrated by one of Imam Malik's prominent shaykhs.
